Morgan celebrated his triumph with a Twitter post, sharing a photo with fans from his Monday night stand-up show at the Comedy Cellar in New York.
“My first time on stage in 16 months at the #ComedyCellar!” he tweeted. “Picking up the pieces!”
In the photo, the 46-year-old is shown performing on stage without any assistance.
The 30 Rock star was first seen walking without a cane or any other help in July and told PEOPLE that his wife and daughter were his inspiration to recuperate.
“I want to walk my wife down the aisle,” he said before the two married in August. “I am determined to play with my little daughter and chase her around.”
The actor joked that he had “started to feel like myself again, which means a whole lot of women are going to get pregnant at the after party.”
Morgan will return to Saturday Night Live to host on Saturday.
