Michigan center Mitch McGary will miss Friday night's season opener against UMass-Lowell because of a lingering back problem.

Coach John Beilein didn't offer many details about McGary's condition or progress. The 6-foot-10 sophomore was named to the AP's preseason All-America team, but it's not clear when he'll be able to take the court this season. The seventh-ranked Wolverines will raise a banner Friday before the game to commemorate last season's run to the Final Four.

McGary averaged 7.5 points per game last season as a freshman, but in the NCAA tournament he averaged 14.3 points and 10.7 rebounds, helping the Wolverines reach the national championship game, which they lost to Louisville.
