ET caught up with Morgan and his wife, Megan Wollover, on the set of his new ad, where the comedian opened up about his journey, and what helped him during his healing process.
"I remember this time last year I was in a wheelchair wondering if I was gonna walk again," Morgan shared. "Now I'm doing a Foot Locker commercial."
According to the former 30 Rock star, a critical part of his recovery was his 2-year-old daughter, Maven, who he shares with Wollover.
"She made me laugh a lot during my therapy," Morgan recounted, smiling. "She loved daddy, and she made daddy laugh a lot."
Morgan and his family have gone from working to help him heal to working on the set of his new commercial.
"She was my rock. [She] still is. She was right there telling me, 'Don't worry about it,'" he gushed. "All she kept saying was, 'I love you,' and, 'Don't worry about it, you're gonna be better than ever.'"
Wollover, 28, told ET that Morgan is "even funnier" than he was before, and that he is "back to [being] himself."
As for the SNL alum, the entire experience has lead him to have a new perspective on life, and to realize what is truly important.
"The things that worried me and that were important before, aren't so important now," Morgan said. "When you spend weeks in comas, then you hear and see things differently. I see life differently. I embrace it more."
"And to my fans, I'm glad I was able to come back and finish the job of making them laugh," he added. "This is for you."
Morgan's new commercial is for Foot Locker's "Week of Greatness" campaign, and it's hard to think of a more inspiring star to represent greatness and perseverance than him.
