Kyrie Irving felt a pop in his left knee after injuring it in the third quarter of the Cleveland Cavaliers' 91-76 loss to the Indiana Pacers on Tuesday.

Irving felt weak following his return to the game, despite being helped to the locker room without putting pressure on his left leg.

"I thought the worst had happened," Irving said. "My left knee is pretty weak right now. I was falling all over the place. I didn't have my legs under me."

Irving missed 38 games over the past two seasons. A long-term injury to Irving could change the direction of the Cavaliers.
