ANN ARBOR, Mich. -- Michigan star Mitch McGary is out indefinitely after deciding to have surgery on his lower back.

Coach John Beilein announced McGary's status Friday, the day before the Wolverines were scheduled to host Holy Cross. McGary missed the first two games of the season because of the injury. In eight games since then, he's averaged 9.5 points.

The 6-foot-10 McGary did not play in Michigan's 68-65 win against Stanford last weekend.

McGary says in a statement that his back problems have been a daily challenge since late August, and that he thought things were moving in the right direction until the past two weeks.

Michigan says there is no timetable for McGary's return, although the medical staff expects a full recovery.
