Minnesota coach Jerry Kill was hospitalized Saturday after having his fourth game-day seizure since taking over as coach in 2011.
Kill, who has epilepsy, was taken off the field on a stretcher at halftime of Saturday's game against Western Illinois. He was lying on the ground, writhing back and forth while surrounded by medical staff as the team headed for the locker room with a 7-6 lead.
The school said Kill was resting comfortably in a hospital.
Doctors have worked with him in trying to control his seizures with medication, rest, nutrition and exercise.
Kill had a seizure in the locker room at halftime against Michigan State last November. He also had seizures after losing to Northwestern last October and in September 2011 near the end a loss to New Mexico State.
He has had other epileptic-related episodes away from football.
The school was aware of Kill's condition when it hired him and has insisted it does not affect his ability to successfully coach the team.
When Kill was at Southern Illinois, he had seizures on game days in 2001 and 2005.
