Nick Gehlfuss who played Dr. Will Halstead on Chicago Med left the show in the season 8 finale. In the episode, Will and Grace sabotaged the defective OR 2.0 tech during Jack Dayton’s hernia repair, but Will took full responsibility for the incident, leading him to resign from the hospital.
There has been no confirmation that Nick Gehlfuss is leaving Chicago Med. However, there are clues that Season 8 could be his last. In Season 8, Episode 2, “Might Feel Like It’s Time for a Change,” Will broke up with Dr. Grace Song because he didn’t think it was a good idea to pursue a workplace romance with her.
