Who left FBI show? Complete Cast Departure Guide and Latest Season 9 Status

Who left FBI show is a question fans continue to ask as the CBS crime drama enters Season 9 with a refreshed team and several major cast changes behind it. The latest confirmed update is that the current core cast remains intact for Season 9, while several notable actors who once played key members of the New York FBI team have already departed.

CBS premiered FBI Season 9 on October 5, 2026, with the series moving to the 8 p.m. ET/PT time slot. The new season brings back Missy Peregrym as Maggie Bell, Zeeko Zaki as Omar Adom “OA” Zidan, Jeremy Sisto as Jubal Valentine, Alana De La Garza as Isobel Castille, John Boyd as Stuart Scola and Juliana Aidén Martinez as Eva Ramos.

That means the biggest departures from the show’s established cast happened before the current season. Katherine Renee Kane, who played Tiffany Wallace, is the most recent major series regular to leave. Lisette Olivera also had a short run as Syd Ortiz during Season 7 before departing.

Several earlier cast members also left during the show’s run, including Ebonée Noel, Sela Ward and Connie Nielsen.

Katherine Renee Kane Left FBI as Tiffany Wallace

Katherine Renee Kane is the most recent major cast member to leave the original FBI series.

Kane joined the drama during Season 3 as Special Agent Tiffany Wallace. Her character became an important part of the team’s field operations and developed a particularly strong professional relationship with Stuart Scola, played by John Boyd.

After four seasons with the series, Kane announced that she would leave during Season 7. She said the decision was connected to wanting to pursue new creative opportunities.

The show addressed Tiffany’s departure at the beginning of Season 7. Rather than killing off the character, the writers gave Tiffany a personal reason to move on from the New York team.

Tiffany decided to leave the FBI team and move to Georgia to be closer to her sister. Her exit allowed the series to introduce another character into Scola’s professional orbit.

Kane’s departure was significant because Tiffany had become a familiar face on the show. She had also become closely connected to several of the show’s long-running characters.

When did Tiffany Wallace leave?

Tiffany Wallace’s final run as a series regular came with Season 7.

Kane appeared in the Season 7 premiere, which served as the character’s departure episode. Tiffany had already decided to leave before the episode’s main investigation began.

Her final storyline gave viewers an explanation for her decision without permanently closing the door through a death storyline.

Kane’s departure was also confirmed publicly before Season 7 began. She said she was looking toward new creative endeavors and wished the series well.

As of the start of Season 9, Tiffany Wallace is not part of the regular FBI team.

Lisette Olivera Also Left After a Short Run

Lisette Olivera became part of the cast shortly after Kane’s departure.

Olivera was introduced as Sydney “Syd” Ortiz, a Behavioral Analysis Unit agent who moved into field work. The character was positioned as a new professional partner for Scola following Tiffany’s exit.

However, Olivera’s time on the show was much shorter than initially expected.

She appeared in only a handful of Season 7 episodes before leaving the series. Reports at the time confirmed that Olivera was no longer continuing as a series regular.

Syd’s departure created another change around Scola. The series subsequently moved in a different direction with its team structure.

Olivera’s exit is therefore important when discussing the show’s recent cast changes, but it should not be confused with Kane’s departure. Kane had a multi-season run as a major character, while Olivera’s appearance was brief.

Ebonée Noel Was One of the Original FBI Cast Members to Leave

Ebonée Noel played Special Agent Kristen Chazal, one of the original members of the FBI team.

Kristen initially worked as an analyst before moving toward field-agent responsibilities. Her character became part of the show’s early development and worked closely with other members of the New York office.

Noel left the series after Season 2.

The character’s departure became a talking point among viewers because the show did not give fans a large farewell storyline. In Season 3, the series explained that Kristen had moved to the Dallas field office.

That explanation allowed the character to leave without being killed off.

Noel’s exit also opened space for the introduction of Stuart Scola, played by John Boyd, as a more prominent member of the team.

Boyd joined the show during Season 2 and eventually became one of its longest-running cast members. Scola later became closely associated with Tiffany Wallace, Syd Ortiz and Eva Ramos as the series continued changing his character’s professional partnerships.

Why did Kristen leave FBI?

The confirmed information is more limited regarding the reason behind Ebonée Noel’s departure.

The series established that Kristen transferred to the Dallas field office. However, there has not been a confirmed public explanation from the actress or CBS that establishes a specific behind-the-scenes reason for her exit.

For that reason, claims about an undisclosed dispute, controversy or other personal reason should not be treated as established fact.

The important confirmed point is that Noel left after Season 2 and Kristen was written as having transferred to Dallas.

Sela Ward Left After the First Season

Sela Ward was another major early departure from FBI.

Ward played Special Agent in Charge Dana Mosier during the show’s first season. Mosier served as the senior leader of the New York field office and oversaw the team during the series’ first year.

Ward did not continue into Season 2.

Her departure led to one of the show’s biggest early changes because Alana De La Garza took on a much larger role as Isobel Castille.

Isobel had appeared during the first season, but De La Garza became a regular cast member in Season 2. She eventually became the team’s Special Agent in Charge.

That transition established the leadership structure that became familiar to viewers over subsequent seasons.

Who replaced Sela Ward on FBI?

Alana De La Garza effectively filled the leadership gap created by Sela Ward’s departure.

De La Garza’s Isobel Castille became a central figure in the New York office and has remained with the series through the current era.

Her continued presence is particularly important because Isobel is still part of the main cast in Season 9.

Therefore, Ward’s departure was not simply a loss for the series. It also marked the beginning of Isobel’s long-term development as one of the show’s principal characters.

Connie Nielsen Left After the FBI Pilot

Connie Nielsen has the distinction of being part of the original FBI cast but leaving almost immediately.

Nielsen played Ellen Solberg, the Special Agent in Charge of the New York field office in the show’s pilot episode.

However, Nielsen did not continue with the series after the pilot.

The character was subsequently replaced by Dana Mosier, played by Sela Ward.

This means viewers who remember the earliest version of FBI may notice that the leadership character in the pilot differs from the one who appears throughout the first season.

Nielsen’s exit happened before the show had established its long-term cast structure.

Because she appeared only in the pilot, her departure is very different from later exits involving actors who spent several seasons on the series.

The Current FBI Cast Has Not Lost Its Main Stars

Despite the number of former cast members, the central group remains remarkably stable.

Season 9 officially brings back the show’s major longtime stars.

The current core includes:

This is important because online discussions have sometimes created confusion about whether long-running stars are leaving.

The Season 9 premiere confirms that Peregrym, Zaki, Sisto, De La Garza, Boyd and Martinez remain part of the show’s current lineup.

Is Zeeko Zaki Leaving FBI?

No. Zeeko Zaki remains part of FBI in Season 9.

Zaki plays Special Agent Omar Adom “OA” Zidan, one of the show’s most recognizable characters. He has been part of the series since its beginning.

The Season 8 finale created a major storyline involving OA’s future with the FBI. That storyline continued into Season 9 and caused some viewers to wonder whether Zaki was actually leaving the series.

He is not.

Season 9 instead uses OA’s situation as part of the show’s ongoing story. The character begins the new season in a different professional position while Maggie works with a new partner.

The change is therefore a story development rather than an actor departure.

Is Missy Peregrym Leaving FBI?

No. Missy Peregrym remains in the series as Maggie Bell.

Peregrym has been one of the show’s principal stars since the premiere in 2018.

Season 9 continues Maggie’s story and introduces a new professional dynamic for her because OA’s circumstances have changed.

Roland Buck III joins the Season 9 cast as Isaiah Green, who works with Maggie as her new partner at the beginning of the season.

That development does not mean Maggie has left the FBI team or that Peregrym has exited the series.

The Season 9 premiere places Maggie at the center of the team’s investigation and confirms that she remains one of the show’s primary characters.

Is Jeremy Sisto Leaving FBI?

Jeremy Sisto also remains with the show.

Sisto plays Assistant Special Agent in Charge Jubal Valentine, a character who has been part of FBI since the beginning.

Jubal has served as one of the team’s key supervisors and has frequently connected the field agents with the wider FBI operation.

There is no confirmed Season 9 departure for Sisto.

The current official cast information continues to identify him as part of the main ensemble.

Is Alana De La Garza Leaving FBI?

Alana De La Garza remains in the series as Isobel Castille.

There has been speculation in the past because the show gave Isobel storylines that could have supported a future retirement. However, those story developments did not result in her departure.

Season 9 continues to feature De La Garza.

Isobel remains an important leader within the New York field office and continues to play a central role in the team’s cases.

Any claim that De La Garza has already left the series does not match the confirmed Season 9 cast information.

Is John Boyd Leaving FBI?

John Boyd continues to play Stuart Scola.

Boyd joined the show during its second season and became one of the longest-serving members of the ensemble.

Scola’s character has experienced several partner changes over the years. Those changes sometimes caused viewers to wonder whether Boyd himself might leave.

However, Scola remains part of the Season 9 team.

The current season also gives the character opportunities to interact with other parts of the Dick Wolf television universe through crossover material involving CIA.

Why Does FBI Have So Many Cast Changes?

Long-running procedural dramas often change their casts as characters complete story arcs, actors pursue other projects or producers introduce new characters.

FBI has followed that pattern without replacing its entire ensemble at once.

The biggest changes have generally involved individual characters rather than the entire team.

The sequence is easy to track:

• Connie Nielsen left after the pilot.
• Sela Ward left after Season 1.
• Ebonée Noel left after Season 2.
• Katherine Renee Kane left during Season 7.
• Lisette Olivera joined during Season 7 but departed after a short run.
• Juliana Aidén Martinez joined the main cast as Eva Ramos in Season 8.
• The principal cast remains together for Season 9.

This gradual approach has allowed the series to refresh its characters while retaining several familiar faces.

Who Left FBI Show and Who Is Still There?

The answer depends on whether the question refers to the show’s entire history or the current Season 9 cast.

Historically, several notable performers have left.

The most recent major series regular departure was Katherine Renee Kane. Before her came Ebonée Noel and Sela Ward, while Connie Nielsen departed after the pilot.

At the same time, the current core cast has remained stable entering Season 9.

Missy Peregrym, Zeeko Zaki, Jeremy Sisto, Alana De La Garza, John Boyd and Juliana Aidén Martinez all remain connected to the current series.

That distinction is important when reading social media posts or older articles about the show. A report about a former cast member can easily appear current even when the departure happened several seasons earlier.

What Changed in Season 9?

Season 9 began on October 5, 2026, and introduced a new professional setup for Maggie and OA.

The premiere, titled “Rendition,” follows the team as it investigates the death of a young traveler connected to a secret government project.

Maggie works with Isaiah Green, played by Roland Buck III, while OA’s storyline moves in another direction.

The season also strengthens the connection between FBI and CBS’ CIA. Necar Zadegan’s Nikki Reynard appears in the Season 9 premiere, while John Boyd’s Scola crosses over into CIA.

These changes represent a shift in the show’s current storytelling, but they do not represent a mass cast departure.

The six established core stars remain the foundation of the series.

What Fans Should Know About Former FBI Characters

Not every actor who has disappeared from the series has been killed off.

That distinction matters because FBI has used transfers and career changes to explain several departures.

Kristen Chazal moved to the Dallas field office.

Tiffany Wallace moved to Georgia to be closer to family.

Sela Ward’s Dana Mosier completed her time as the New York office’s leader, after which Isobel Castille took over.

Syd Ortiz had a short run before leaving the series.

These exits allowed the show to continue without forcing every departure into a dramatic death storyline.

That approach has also left room for the possibility of characters returning in guest appearances, although no unsupported return should be treated as confirmed.

What Is the Latest Confirmed FBI Cast Status?

As of October 6, 2026, FBI is in its ninth season.

The latest confirmed status is straightforward: the show’s major current stars are still present.

The most significant recent departure remains Katherine Renee Kane’s Tiffany Wallace, while Lisette Olivera’s short-lived Syd Ortiz run also belongs to the recent history of the series.

Earlier departures include Ebonée Noel, Sela Ward and Connie Nielsen.

Meanwhile, Maggie Bell, OA Zidan, Jubal Valentine, Isobel Castille, Stuart Scola and Eva Ramos continue to form the core team.

The Season 9 premiere has therefore settled several questions that circulated around the show’s cast. OA has not left the series, Maggie has not been written out, and the longtime leadership characters remain active.
