Friday's edition of The Tonight Show was canceled after host Jimmy Fallon injured his hand and underwent surgery to repair the damage.

"Tweeting with one hand," the 40-year-old comedian posted in a message, alongside a photo of his bandaged fingers.

"Tripped and caught my fall (good thing)! Ring caught on side of table almost ripped my finger off (bad thing)," he tweeted.

"#drugged #blessed," read another message. "I'm doing well and thanks for good wishes everyone."

"Hey guys - unfortunately tonight's taping has been cancelled due to Jimmy injuring his hand. He's totally fine but we'll be airing a repeat," said a Friday post from The Tonight Show Twitter account. "If you had tickets to tonight's show, we'll be in contact with you to reschedule your tix."
