Mark Harmon, who portrayed Special Agent Leroy Jethro Gibbs from Season 1 to Season 19 of CBS’s procedural drama “NCIS,” left the series in a significant shift for the show. Harmon’s departure has left fans curious about the reasons behind his exit and the fate of his character.

Since leaving “NCIS,” Harmon has not taken on any new roles but signed with The Gersh Agency in 2023, suggesting potential future opportunities. Despite Gibbs no longer being a regular presence, the possibility of special appearances remains open.
