Spencer, who exited the NBC drama last October, is in talks to reprise his firefighter Matt Casey role. "I talked to him last week so I’m very hopeful that that’s going happen," says co-showrunner Derek Haas.

Jesse Spencer to Return for "Chicago Fire" Season 10 Finale, but No Monica Raymund

Jesse Spencer will return as Matt Casey next month for the Season 10 finale of NBC’s "Chicago Fire". Spencer exited the series in October after a decade on the firefighter drama.
Casey has good reason to return for this specific episode, which series executive producer Derek Haas refers to as, “pretty epic.” At long last, fans will see the wedding of Severide (Taylor Kinney) and Stella Kidd (Miranda Rae Mayo).
“The juicy details are that we went to him and said, ‘You’re so loved on this show. And with the Severide wedding coming up, there’s no way Casey would miss seeing his best friend getting married. Come on, man!’ So, he graciously agreed to come back for the finale,” Haas told Deadline.
Milestone celebrations tend to bring people together from all over the world, which begs the question, could Monica Raymund also return?
Haas and Raymund have remained close since she exited the series at the end of Season 6; she’s even made a couple of reappearances as Gabby Dawson. Could Casey’s ex also attend?
“I actually spoke to Monica [on Monday], she’s directing an episode of my friend’s upcoming TV series National Treasure. So she’s busy,” Haas said. “She’s been directing a lot. She’s put Dawson behind her. Andrea and I convinced her to come back a few times but I don’t think she’s going to come back anytime soon.”
