Michigan offensive lineman Graham Glasgow has been suspended for a portion of spring practice and for the team's season opener against Appalachian State, the school announced Thursday.
The suspension stems from "a violation of team expectations," according to a team news release.
Glasgow, a junior, started all 13 games last year for the Wolverines, including nine at center and four at left guard.
Michigan's offensive line struggled last season, and rebuilding the unit has been a major focus of spring practice.
