Current Status for 2025
As of early 2025, Mark Harmon has not returned to NCIS in a full-time acting capacity, and he will not appear in new episodes this season. NCIS is currently airing its twenty-second season in its long-running Tuesday timeslot on CBS. Harmon last appeared in the Season 21 finale in May 2024. The show has continued without him through the start of Season 22, and showrunners have not announced plans to bring him back for the balance of the 2024–25 season. This summary explains what has changed, what has stayed the same, and what viewers can reasonably expect moving forward.
What Has Changed Recently
Season 21 Exit
In May 2024, NCIS aired its Season 21 finale, which marked the last regular appearance of Special Agent Leroy Jethro Gibbs, played by Mark Harmon. The finale deliberately concluded a major arc for the character, giving the series a narrative off-ramp to explore the team’s future without Gibbs. That shift was reflected in casting notices, press coverage, and on-air storytelling, signaling a transition rather than a temporary leave.
Season 22 Production Timeline
NCIS began production on Season 22 well before Harmon’s exit was public, which meant the season was largely built around the existing ensemble. By the time filming started for the 2024–25 season, the scripts and shooting schedules were finalized without a built-in mechanism for Harmon to return. Showrunner Frank Military has overseen a steady production pace, and no last-minute changes have been reported that would accommodate Harmon’s schedule. This structural detail explains why a return during Season 22 is unlikely.
Behind the Scenes: How NCIS Has Adapted
Leadership and Team Structure
With Gibbs absent, NCIS has shifted leadership emphasis toward other senior figures. Characters such as Special Agent Timothy McGee, now promoted to team leader, and new additions to the supporting cast carry more on-screen responsibility. This recalibration allows the series to maintain its procedural format while adjusting the group dynamic. The writing room has leaned into ensemble storytelling, reducing dependence on any single character’s desk-jockey presence.
Casting and Recurring Roles
The show has introduced new regular and recurring characters to fill narrative space. These additions include fresh field agents, support staff, and administrative personnel who interact with the team on a case-by-case basis. While none replicate Gibbs’ exact role, they provide new avenues for conflict, mentorship, and humor. This approach demonstrates how NCIS can refresh its storytelling without relying on a legacy figure’s return.
Official Information and Sources
CBS and showrunners have issued statements aligning with the on-air progression. Press conversations and studio comments confirm that Season 22 continues without plans to rewrite existing episodes or reshoot material for Harmon. Press tours, official show pages, and trade reporting all consistently point to a firm division between Season 21 as Harmon’s farewell and the ongoing Season 22 storyline. The table below summarizes the key details.

Addressing Fan Expectations and Rumors
Throughout television seasons, fan forums and entertainment chatter often revive hope for a departed star’s return. For NCIS, speculation about Harmon’s return typically arises around milestone episodes or holiday sweeps. However, there is no evidence of ongoing negotiations, table reads, or script development that would indicate such a move. Industry reporting and trade outlets have not cited any active discussions, and no casting calls or studio announcements point to a reversal of the Season 21 conclusion.
What Viewers Can Expect Going Forward
NCIS is positioned as a continuing ensemble series with a stable cast that has been developing for decades. The procedural format, rooted in case-of-the-week storytelling, allows the show to evolve without requiring a central figure’s constant presence. Viewers can anticipate ongoing investigations, character-driven subplots, and new dynamics shaped by the current roster. While Gibbs’ absence leaves a noticeable gap, the series is built to adapt, and its long history suggests that the show will continue to find new ways to resonate without reverting to past configurations.
