Freeman, a junior guard, started Saturday's Big East regular season finale against Cincinnati. He was given a standing ovation before the game when recognized for scoring his 1,000th career point earlier this season and another standing ovation when announced with the starting lineup.
Freeman, the team's leading scorer, was thought to have a stomach virus when he missed Monday's loss to West Virginia and was limited in a loss to Notre Dame two days earlier. He was diagnosed with diabetes at a hospital Monday night.
As a precaution, a doctor from the university's hospital is attending Freeman's practices and games for the rest of the season.
