Schiano said Williams decided to leave the team after some depth chart changes were made at his position.
"We made some depth-chart changes, which I didn't go into the specifics of it [with the media], but one of them was in the running back position and De'Antwan decided that ... he's not agreeing with it," Schiano said. "Right now, he's decided to leave the team. Again, the door is open. We're going to care a lot about him. I just wish that he would keep competing and stay at it. He feels like it's not right. Again, everybody has an opinion on how things should be done. Right now, he's not not with the program."
Williams averaged nearly seven yards per carry against Football Championship Subdivision foes in his career and scored his only career touchdown as a true freshman against Texas Southern.
Rutgers, however, faces Ohio next week and solely Division 1 opponents the rest of the season and Williams' numbers against tougher opponents are not as impressive. In parts of three seasons, Williams averages 1.7 yards per carry against FBS teams.
Williams transfer makes Huggins, who shared an "or" on the depth chart the expected starter for Ohio, with Deering and red-shirt freshman Jawan Jamison likely to see increased workloads.
"I'm kind of sad to see De'Antwan go," said sophomore center David Osei. "He's a real close friend of mine. He was my first roommate of college. It's sad to see him go, but it's the kind of thing where there is so much talent anyway. The team will step up. People will step up."
