Confirmed Main Cast Departures
Over its fourteen-season run, NCIS: Los Angeles has seen several main cast members depart, with reasons ranging from creative decisions to personal circumstances. Below is a concise summary of the most notable exits and their narrative consequences within the series.
Chris O’Donnell as Grisha ‘G’ Callen
Portrayed by Chris O’Donnell, Callen remains the central figure despite production gaps and reduced screen time in later seasons. O’Donnell has intermittently scaled back his schedule while maintaining a presence, framing Callen as a linchpin even during fluctuating episode commitments.
Daniela Ruah as Kensi Blye
Daniela Ruah exited the regular cast after season 13, transitioning to a recurring role to pursue other opportunities. Her departure marked the end of a long-running partnership with Callen, shifting team dynamics and prompting new field and support structures within the unit.
Eric Christian Olsen as Marty Deeks
After ten seasons as a series regular, Olsen moved to recurring status starting in season 14 and exited fully after season 18. His character’s arc concluded with a narrative that allowed for future appearances, preserving Deeks’ established relationships offscreen.
Michele McPhee as LAPD Liaison Devin Roundtree
Introduced as LAPD liaison in season 19, McPhee appeared across multiple episodes in a story arc before leaving the series. This exit reflected shifting command structures within the LAPD partnership rather than a reduction in overall ensemble size.
