The Cast Members Leaving ‘Chicago Med’ in 2026
The halls of Gaffney Chicago Medical Center are undergoing substantial roster adjustments as ‘Chicago Med‘ transitions between its eleventh and twelfth seasons in 2026. Longtime viewers are preparing to bid farewell to several familiar faces, ranging from original day-one personnel to recent additions whose storylines are coming to a close.
Whether driven by personal decisions from the cast members or dramatic narrative developments, these departures will reshape the hospital’s dynamic moving forward. Here is a breakdown of the notable cast members exiting or stepping away from the series during this major transitional period.
Ashlei Sharpe Chestnut – Naomi Howard
Ashlei Sharpe Chestnut officially departed from ‘Chicago Med’ ahead of the premiere of Season 12. The actress confirmed during the summer hiatus that walking away from the medical drama was a personal decision. Her exit means that her character, Naomi Howard, will not return to continue her developing romantic relationship with Dr. Frost. Chestnut’s departure concludes her tenure on the program just as her character was becoming more deeply integrated into the emergency department’s core narrative.
Marlyne Barrett – Maggie Lockwood
Original cast member Marlyne Barrett has stepped down from her longtime role on ‘Chicago Med’ due to personal reasons. Her character, Charge Nurse Maggie Lockwood, served as an essential anchor of Gaffney Chicago Medical Center since the pilot episode. The veteran nurse was officially written out at the start of the television cycle, marking the end of a pivotal day-one presence. Barrett’s departure leaves a substantial operational and emotional void within the emergency department that new leadership must now address.
Dominic Rains – Dr. Crockett Marcel
Dominic Rains concluded his tenure as a series regular on ‘Chicago Med’ following a dramatic narrative arc centered around the loss of a young patient. Although his on-screen departure occurred at the conclusion of Season 9, his permanent absence continues to reverberate through the 2025–2026 cast reorganizations. The trauma surgeon’s grief-stricken choice to step away from the surgical unit concluded several seasons of intense emergency room storylines. His status as an exited regular remains one of the defining shifts shaping the hospital’s ongoing medical roster.
S. Epatha Merkerson – Sharon Goodwin
Longtime hospital administrator Sharon Goodwin faces a storyline-driven exit after taking responsibility for leaked medical records in the Season 11 finale of ‘Chicago Med’. Following her decision to fall on the sword, Goodwin is temporarily suspended from her executive duties to kick off Season 12. A new, bottom-line-driven director named Malorie Sloane steps in to assume control of Gaffney Chicago Medical Center during her absence. While actress S. Epatha Merkerson is not permanently leaving the series, her character must navigate a fierce battle to reclaim her administrative post.
