Tressel made eight BCS games, won the last six Big Ten championships and the 2002 national title, but his career record at OSU will stop at 106-22.
Assistant head coach and linebackers coach Luke Fickell will take over for the 2011 season, the university announced.
Fickell was set to take over anyway for the first five games, the suspension levied against Tressel for not divulging to the NCAA that he knew about the players memorabilia sales but did not alert the compliance department or any other higher ups at OSU.
In the meantime, more revelations about what Tressel knew have leaked out, and stories -- as yet unproven -- about other benefits provided to players have continued to appear.
Stay tuned for more on this breaking news. The text of the Ohio State announcement, in full, follows:
Columbus, OH – The Ohio State University announced today that it has accepted the resignation of Jim Tressel as head coach of its football program. Luke Fickell will serve as interim head coach for the 2011-2012 football season. Recruitment for a new head coach – which is expected to include external and internal candidates – will not commence until the conclusion of the 2011-2012 season.
"In consultation with the senior leadership of the Board of Trustees, I have been actively reviewing matters attendant to our football program, and I have accepted Coach Tressel's resignation," said President E. Gordon Gee. "The University's enduring public purposes and its tradition of excellence continue to guide our actions."
Jim Tressel said, "After meeting with University officials, we agreed that it is in the best interest of Ohio State that I resign as head football coach. The appreciation that Ellen and I have for the Buckeye Nation is immeasurable."
Athletics Director Gene Smith said, "We look forward to refocusing the football program on doing what we do best – representing this extraordinary University and its values on the field, in the classroom, and in life. We look forward to supporting Luke Fickell in his role as our football coach. We have full confidence in his ability to lead our football program."
