Dwayne Johnson Steps in for Pal Kevin Hart as 'First Guest Ever' on 'The Kelly Clarkson Show'
"Kevin's spinal injuries are very serious, he sustained several fractures and had no choice but to have surgery as soon as possible," the source says. "Since the surgery, he has been heavily sedated. The physicians are doing everything they can to keep him out of pain."
ET spoke with Hart's close friend and frequent co-star, Tiffany Haddish, at the Harper's Bazaar ICONS event at The Plaza Hotel in New York City on Friday, and the Night School actress shared, "He's OK. He's doing fine. As far as I know, from the last I heard, he's fine."
Haddish added, "He's already walking. He's good," but admitted that his "back's gonna hurt" even after he eventually gets out. Hear more in the video below.
