The school released a statement Saturday night saying police were called after the team finished practice. McGloin was treated at Mount Nittany Medical Center.
McGloin's father, Paul, told the Patriot-News of Harrisburg and the Pittsburgh Post-Gazette that his son suffered a seizure and a possible concussion but was back at his campus apartment. Messages left Saturday night by The Associated Press for Paul and Matt McGloin were not immediately returned.
The school said campus police and judicial affairs would investigate.
