Wolverines head coach Rich Rodriguez said in a statement Saturday that Feagin's violation occurred Thursday night.
The 6-foot, 198-pound Feagin came to Michigan as a quarterback and was a candidate for the starting job last season before being moved to slot receiver. He appeared in four games as a reserve quarterback in 2008 and had 11 rushes for 52 yards, including a 34-yarder in a win against Minnesota.
Michigan has had a swell of player departures during Rodriguez's brief tenure, though Feagin is one of the first players exclusively recruited by Rodriguez's staff to be leaving the program. Offensive lineman Dann O'Neill recently transferred to Western Michigan, and offensive lineman Kurt Wermers announced his transfer to Ball State last week.
