CLEVELAND – Kyrie Irving, the NBA's reigning rookie of the year, broke his right hand during the Cavaliers' practice on Saturday in Las Vegas.

Irving will return to Cleveland to be examined by team doctors Sunday and said he likely will undergo surgery. The Cavs said in a release Saturday night that they expect Irving, their leading scorer last season who recently dazzled during scrimmages against the U.S. Olympic team, to be ready for the start of training camp in late September. However, the team said it will not have a timeline for Irving's return until after he is examined.

The team said Irving injured his hand slapping the padding on a wall at the team's practice site. The injury occurred after Irving committed a turnover toward the end of the morning practice. Irving was in Las Vegas practicing with Cleveland's summer league team.
