Sixteen-time world heavyweight pro wrestling champion Ric Flair learned Wednesday that he will have to undergo surgery next week for a torn left triceps.

Flair, 62, suffered the injury during a match with Sting last week on TNA’s weekly Impact show. Initially Flair was told that the injury was limited to a broken bursa sac in his left elbow.

“I thought it was getting better but the swelling just wouldn’t go away,” Flair said Wednesday night.

Flair, who was at Boston’s Fenway Park on Tuesday to throw out the first pitch and present Red Sox players Dustin Pedroia and Josh Reddick with replica TNA title belts, said the pain had increased in recent days. “When I threw Tuesday, the arm blew up to about twice the size of the other arm. It’s all black and blue.”

Flair amazingly has suffered few major injuries during his nearly 40 years in the ring.

“I’ve never torn anything in my life except my rotator cuff,” he said. “I just landed on it wrong. And that just comes from not working enough. But it’s no big deal. It could have been a thousand other worse things.”
