OAKLAND, Calif. (AP) _ Cavaliers guard Kyrie Irving has a fractured left knee cap and will have surgery that will end his season.

The Cavaliers said Friday that an MRI exam revealed the injury and that Irving’s projected recovery time was three to four months.

Irving limped off the court during overtime of Cleveland’s 108-100 loss to Golden State on Thursday night in Game 1 of the NBA Finals. He left the arena on crutches, and Cavs coach David Blatt says he heard Irving was still on crutches Friday morning.

Irving missed two games during the Eastern Conference finals but had played well Thursday, finishing with 23 points before leaving.
