Michigan running backs coach Mike Hart collapsed on the sideline at Indiana University Memorial Stadium in the first quarter of the Wolverines' game against the Hoosiers. The former Michigan running back was brought off the field on the medical cart.
Hart holds the record for career rushing yards at Michigan, reaching 5,040 yards in his time there. His protege, RB Blake Corum, has been having a breakout season and started the game with a 50-yard run and a touchdown on the next play.
The cause of Hart's collapse is unclear. Updates to come.
