Kyrie Irving didn't waste a moment in starting his recovery for next season, rushing back from the NBA Finals to have surgery on his left knee.

The Cavaliers' All-Star guard was in the operating room Saturday to repair the broken kneecap he suffered in Game 1, an injury that will make it even tougher for Cleveland to try and win a title.

Irving's surgery at the Cleveland Clinic came less than 24 hours after an MRI revealed the fracture, which had bothered him throughout the postseason. He got hurt in overtime of Cleveland's 108-100 loss to the Golden State Warriors, who will try to take a 2-0 lead in the best-of-seven series at home on Sunday night.

Irving was driving to his right when he crumpled to the floor. Afterward, he said he felt "something different" in his knee and his instincts were right as tests confirmed his fears. It's a difficult blow to the Cavs and a devastating one to Irving, who has been dogged by injuries throughout his pro career.
