Defensive coordinator John Papuchis and offensive coordinator Tim Beck split the head-coaching duties the second half. Pelini said he was released from the hospital late Saturday afternoon and spent the evening at home relaxing.

Pelini is the fourth Big Ten coach to have a health scare in recent seasons.

Ohio State’s Urban Meyer left Florida after the 2010 season because of stress. He complained of chest pains, difficulty sleeping and weight loss.

Michigan State’s Mark Dantonio was hospitalized in 2010 because of a mild heart attack. He had surgery to put a stent in a blocked blood vessel leading to the heart. Minnesota’s Jerry Kill had seizures last season.
