Marlyne Barrett Exits Chicago Med as Series Nears 10-Year Milestone

Marlyne Barrett is leaving the hit NBC series Chicago Med. Her departure coincides with the show’s upcoming 10-year anniversary. The actress played Charge Nurse Maggie Lockwood since the series premiere in 2015.

This exit marks a significant shift for the long-running medical drama. Only two original cast members now remain as the show prepares to celebrate a major legacy milestone.

Barrett’s Final Episode and Cast Reshuffle

Barrett announced her exit in late August 2025. She is stepping away for personal reasons. According to Variety, her character was a cornerstone of the emergency department.

Showrunner Allen MacDonald has indicated her leave could be temporary. This leaves the door open for Maggie Lockwood’s potential return in future episodes.

The timing is particularly poignant. Her departure was confirmed just one day after Nick Gehlfuss announced his guest return as Dr. Will Halstead. This creates a mix of emotions for the dedicated fanbase.

Impact on Chicago Med’s Legacy and Future

Barrett’s exit profoundly changes the dynamic at Gaffney Chicago Medical Center. She was one of only three original cast members still on the show. Her character provided emotional stability and institutional knowledge.

Maggie Lockwood served as the heart of the ED for a decade. She guided new interns and supported senior staff through countless crises. Her absence creates a substantial void in the show’s core identity.

The series must now navigate its milestone season without a key original player. This tests the resilience of the long-running One Chicago franchise. The remaining original cast, S. Epatha Merkerson and Oliver Platt, now carry the show’s foundational legacy.

Chicago Med continues its eleventh season amid these significant cast changes. The show’s ability to evolve will determine its future beyond this celebratory year.
