No reason was given for Stonum's suspension, but coach Brady Hoke said in a statement that Stonum must "fulfill all his commitments he has to the legal system and our program" before he could have a chance to be reinstated. Stonum was arrested for DUI in September 2008 and spent three nights in jail last June for probation violations.
Officials for University of Michigan police and Ann Arbor police reported no known incidents involving Stonum when reached by ESPN.com on Saturday.
"Darryl made a poor decision that is unacceptable and won't be tolerated," Hoke said in a statement released Saturday. "He will be disciplined for behavior that is unbecoming of a Michigan football player. This is a serious situation. We are disappointed and any athletic department discipline will be handled internally. We will provide the appropriate support and counseling in order for him to learn and grow from this mistake."
Stonum was the team's No. 2 receiver in 2010, racking up 49 receptions for 633 receiving yards and four touchdowns. He would be missed if he's not reinstated for the season, although Michigan still boasts All-Big Ten candidate Roy Roundtree, Junior Hemingway, Kelvin Grady and Martavious Odoms.
