Hare's departure comes hours before URI's season-opening game against Pace University; the school did not offer a reason for Hare's decision to break ties with the program.
He did not appear during the media portion of the team's Wednesday practice this week. Hare also missed all of last season in order to attend to personal issues in the 6-foot-10 redshirt sophomore's native Michigan.
Hare performed well as a freshman two seasons ago, averaging 4 rebounds, 1.8 blocks per game and 5.2 points on 58.5 percent shooting. That season, Dan Hurley's first season as head coach, he started 19 games, helping the team to a final record of 8-21.
Hare was a top-150 recruit who committed to URI while Jim Baron was head coach. After Baron's firing, he was persuaded to honor his commitment by Hurley and former URI assistant coach Preston Murphy.
