The 46-year-old comedian was spotted on the set of his upcoming film, Fist Fight, in Atlanta, Georgia on Thursday, shooting scenes for his role as a football coach.
Morgan was seen being escorted onto a football field on a golf cart to film his scenes in the comedy, which also stars Ice Cube and Charlie Day. An eyewitness told ET that the comedian "still is not 100%," and was slow getting out of the golf cart at one point, appearing to be in pain.
"He never stood for too long," the eyewitness said. "However, for the most part, he looked healthy and excited to be working again. Tracy was joking around with the kids in the movie and laughed with crew."
The comedian made a surprise appearance at the Emmy Awards last month, presenting the final award of the night for Best Drama Series and giving his first public remarks since the June 2014 car crash that killed Morgan’s friend and fellow passenger, James McNair, and left the 30 Rock star comatose with a traumatic brain injury.

"When you have traumatic brain damage -- as you can see the scars on my head -- at that moment it first happened, when I didn't see any hope and I couldn't walk, before they taught me how to stand up and sit down again, you don’t feel [like you'll recover]," Morgan told reporters backstage after the awards show. "But as the months and the months and the months went by, part of my therapy was seeing TV and seeing my friends and saying that I'm coming back one day. My wife made sure of that."
The Saturday Night Live alum will also return to host the live sketch comedy show on Oct. 17, a feat Morgan’s doctor calls "nothing short of a miracle."
"When I started treating Tracy in June 2014, if someone had told me that he'd be on SNL in October of 2015 I would've had to look at that with great doubt," Dr. Brian Greenwald told the Daily Beast in August. "Unfortunately, so many people don't recover as well as he does."
