Andover High School Principal Philip Conrad announced Tuesday that a school system investigation found the allegations were "not sustained."
Conrad says he will reinstate the coaches if an ongoing investigation by the state Department of Children and Families comes to the same conclusion.
Varsity boys hockey Head Coach Chris Kuchar denied the allegations. He and two assistant coaches were placed on leave last month.
Officials investigated two reported incidents: students not being allowed a water break while being forced to do punitive conditioning during a practice after losing a game, and players being denied food while returning to Andover after losing an away game.
