Indiana University announced the resignation Thursday of athletic director Rick Greenspan effective in December.
Greenspan's resignation comes on the same day the university learned the NCAA Committee on Infractions has added a "failure to monitor" charge to its list of infractions following a hearing in Seattle earlier this month.
According to a letter from the committee released by Indiana, the university "failed to adhere to its self-imposed corrective actions." The letter also charges that IU didn't adequately follow through when it knew that members of the men's basketball staff were not following restrictions placed on them after the Hoosiers hired Kelvin Sampson.
The university and Sampson have been charged with four major violations, including impermissible phone calls and three-way phone calls. Sampson and former assistant Rob Senderoff have contended that the university was never aware of the phone calls.
In a statement Greenspan said: "This has been a very difficult time and I am aware that I have become the focus of criticism which will continue to distract Indiana University from its core educational mission. Consequently I believe a new person will in a stronger position to lead IU athletics moving forward and it is in IU's best interests for me to stand down. You can rest assured that I will work with great diligence and effort on behalf of our student-athletes and coaches. They deserve nothing less."
Of the new charges, Greenspan said: "Without question I am extremely disappointed in the new charges brought by the NCAA Committee on Infractions against Indiana University that were released today. I disagree with these charges, particularly since the NCAA Enforcement staff did not reach this same conclusion after their original, in-depth investigation. Nevertheless, the new charges must and will be answered.''
Indiana president Michael McRobbie vowed to appeal the new charges.
