CLEVELAND (AP) -- Cavaliers guard Kyrie Irving broke his right hand during a practice in Las Vegas and could be sidelined two months.

The NBA's rookie of the year injured his hand slapping the padding on a wall. The Cavs said in a release Saturday night that Irving is returning to Cleveland for further examination on Sunday. The team said it expects him to be ready for the start of training camp in late September, but a timeline for his return will be updated after he is seen by doctors.

Irving's injury is a setback for the No. 1 overall pick in the 2011 draft who dazzled during workouts and scrimmages against the U.S. Olympic team recently.

The 20-year-old Irving missed time as a rookie with a variety of injuries and played in only 11 games as a freshman at Duke because of a toe injury.
