Texas offensive lineman Patrick Hudson was taken to the emergency room Wednesday after suffering a heat illness, coach Tom Herman said.
Herman said the 6-foot-4, 335-pound Hudson had a "full body cramp" and the team's trainers dunked him in a cold bath to get his body temperature down before an ambulance arrived.
Hudson has been released from the ICU after his temperature returned to normal.
Herman said Hudson will not play this week against Tulsa.
Herman suggested doctors are still running tests to find out why Hudson's body temperature spiked when others didn't.
