Nate Johnson was arrested early on Saturday morning and charged with one count of domestic assault for what MLive called “an attack on a female student.” The alleged attack is believed to have occurred in the victim’s dorm room.
Michigan football announced Saturday that Johnson had been “suspended indefinitely from all team activities” in a team release. The sophomore switched from wide receiver to cornerback after his freshman season, and has not recorded any stats yet in 2017. Johnson had 1 reception for 4 yards as a freshman in 2016.
