Another Cast Member Is Leaving 'Chicago Med' -- Who Won't Be Back for Season 10?

More changes are coming to NBC’s One Chicago shows. Dominic Rains will not return to Chicago Med for its upcoming 10th season. 

Dominic Rains exits ‘Chicago Med’ ahead of season 10  

Rains joined Chicago Med in season 5 as Dr. Crockett Marcel. He will not return as a series regular in season 10, Deadline reported. It’s not known if Rains might make a guest appearance next season. Rains’ exit follows the departure of Nick Gehlfuss as Dr. Will Halstead and Brian Tee as Dr. Ethan Choi in season 8.

The Chicago Med Season 9 finale set the stage for Crockett’s departure from Gaffney Chicago Medical Center when he spiraled into crisis following the death of one of his young patients and the subsequent suicide of the boy’s father. The situation unlocked Crockett’s unresolved grief over his own daughter’s death from cancer, and hospital head Sharon Goodwin (S. Epatha Merkerson) told him to take time off. 

While Rains is on his way out, three longtime Chicago Med cast members will return next season. Merkerson, Oliver Platt, and Marlyne Barrett will appear in season 10, according to TVLine. 

Changes are coming to other One Chicago shows 

Rains’ departure isn’t the only change coming to Chicago Med. Co-showrunners Diane Frolov and Andy Schneider are stepping down after nine years. They’ll be replaced by Allen MacDonald.

Change is also in the air at the other One Chicago shows. 

Longtime Chicago Fire cast member Eamonn Walker is exiting as a series regular after 12 seasons. He’s played Chief Wallace Boden since the show premiered in 2012. Kara Killmer, who played Sylvie Brett, and Alberto Rosende, who played Blake Gallo, left earlier in season 12, while Jocelyn Hudon joined the show as paramedic Lyla Novak. 

Meanwhile, Chicago P.D. fans have had to bid farewell to Tracy Spiridakos, who has played Detective Hailey Upton since 2017. Her last episode was the show’s season 11 finale, which aired in May 2024. 

“It was a really hard decision, and I don’t know that there’s ever a right time,” Spiridakos told NBC Insider of her decision to leave Chicago P.D. “I think I’ve been on the show for just over seven years, like seven and a half-ish years, and I was just wanting to switch it up and kind of see what else was out there. That was really it. I’m so close with everybody. With our producers, Gwen, our writers, our cast, our crew. It was a really difficult and emotional time, for sure.”

Though cast changes can be jarring for viewers, they’re to be expected when shows last as long as Chicago Med and its sister series. 

“Cast comes in, cast goes out…,” Jeff Bader, President of Program Planning Strategy for NBCUniversal Entertainment, recently told TVLine. “We’re thrilled with how the Chicagos do on Wednesday. We have no plans on changing anything on that night.”

Chicago Med, Chicago Fire, and Chicago P.D. will also return with new episodes on NBC this fall. 

Chicago Med is streaming on Peacock.
