Michigan basketball's Josh Bartelstein has ankle surgery

Michigan Wolverines basketball captain Josh Bartelstein had surgery on his injured right ankle and will miss six to seven weeks, according to MLive.com's Nick Baumgardner.

Bartelstein, a walk-on, hasn't played since the Wolverines' 91-54 win over IUPUI on Nov. 12. He hasn't had much of an impact on the court this season, playing a total of four minutes and compiling one assist and one steal. Despite his meager numbers, Bartelstein's leadership has been a valuable asset to the Wolverines.

The Wolverines (6-0) are ranked No. 3 in the Associated Press and USA Today Coaches' Polls. Michigan won the NIT Season Tip-Off with victories over IUPUI, Cleveland State, Pittsburgh and Kansas State, and the team is coming off a 79-72 win over No. 18 NC State in the ACC-Big Ten Challenge.

Next up for Michigan is a road date at Bradley. The Wolverines tip off from Carver Arena in Peoria, Ill., Saturday, Dec. 1 at 3 p.m. ET. The game will be televised on ESPNU.
