Michigan State coach Mark Dantonio suffered a heart attack shortly after the conclusion of the Spartans? 34-31 overtime win against Notre Dame Saturday night. MSU confirmed the news this afternoon, and said he was expected to make a ?full recovery,? after undergoing a cardiac catheterization procedure at Lansing?s Sparrow Hospital. Offensive coordinator Don Treadwell will step into the head coaching role while Dantonio recovers.
