Colin Donnell Will Return to Chicago Med as Dr. Connor Rhodes in Season 12

Colin Donnell is set to reprise his role as Dr. Connor Rhodes for two episodes of Chicago Med's twelfth season. His first appearance will be in the fall finale on December 9, when Sharon Goodwin asks him to help a young heart patient who needs a risky operation. Donnell left the NBC drama in the Season 5 premiere after Connor's ex-girlfriend Ava killed his father and then took her own life.
Colin Donnell, an original cast member, played Dr. Connor Rhodes until the Season 5 opener. He will appear in two Season 12 episodes. His first return comes in the fall finale on Dec. 9 at 8/7c, when Sharon Goodwin asks him to assist a young cardiac patient facing a difficult, high-risk procedure.
After Connor learned his ex-girlfriend Ava was responsible for his father's death, and after Ava's suicide, he left Chicago to begin anew. Showrunner Allen MacDonald said Connor's return had been a priority and that the actor's comeback was welcomed.
For longtime Chicago Med viewers, Connor's return may stir nostalgia and renewed interest in the series, potentially boosting live or streaming tune-in around the fall finale. Fans of medical dramas could see it as a payoff to a long-running character arc, while newer viewers might be prompted to revisit earlier seasons. The two-episode visit could also shape online discussion about how shows handle returning characters and unresolved grief.
