CLEVELAND - Cavaliers rookie star Kyrie Irving could miss 10 days after aggravating his sprained right shoulder.

Irving returned after missing one game with the injury and played Tuesday night against San Antonio. The 20-year-old guard worsened his injury after contact and did not accompany the team to Milwaukee for last night's game. The Cavs said Irving underwent an MRI, which revealed a bruise and sprain.

Irving, who wore a protective brace in Tuesday's game, is projected to miss at least one week.

The league's presumptive rookie of the year scored 13 points in the Cavs' 125-90 loss. Cleveland has lost eight straight, and according to STATS LLC, the Cavs are the first team in NBA history to lose consecutive home games by at least 35. Cleveland lost 121-84 to the Bucks on Friday.
