A 19-month NCAA investigation at Missouri resulted in the basketball program vacating all 23 wins from the 2013-14 season and a one-year postseason ban, the university announced Wednesday.
Other sanctions for the Tigers, who have an 8-8 record this season, include the loss of one scholarship in 2015-16 and a second no later than the 2017-18 season, and a $5,000 fine to be paid to the NCAA.
The probe, conducted by the university and the NCAA, found infractions occurred as far back as the 2011 season. The school received a notice of inquiry from the NCAA a few days after coach Frank Haith, the 2012 Associated Press national coach of the year, left for Tulsa in April 2014 with a 76-28 record at Missouri.
The university is cooperating with the NCAA in an attempt to limit the sanctions to those self-imposed by the school. It said there is no evidence that current staff members were aware of any violations.
"We are obviously very disappointed that the actions of a few individuals have put our program in this situation," Tigers coach Kim Anderson said in a statement. "However, I am appreciative to (athletic director) Mack Rhoades and our staff for their guidance and support throughout this process. I hurt for our kids more than anything and for our only senior Ryan Rosburg in particular, but I am confident we will overcome this and be stronger as a team and as a staff because of it.
"We are committed to representing this great university and state with honor and integrity and that's what we are going to do."
According to the NCAA, one unidentified donor provided improper benefits to three players and one recruit in 2013-14 through compensation for work not completed in a summer internship program. The university has since permanently banned the donor.
A second donor who provided transportation for players to a hotel from campus was banned for two years. The program also was cited for failing to monitor its internship program, which is a major infraction.
"It is clear from our collaborative investigation with the NCAA that a former member of our athletics staff and members of our donor community violated NCAA bylaws, and we take those actions seriously,'' Missouri chancellor Hank Foley said.
As a result of the sanctions, Missouri will not participate in the SEC postseason tournament this season.
"Missouri's administration has been diligent in this matter and by all accounts has cooperated fully with the NCAA," SEC commissioner Greg Sankey said. "Missouri has taken appropriate steps based on the information that has been discovered. The SEC will make the necessary adjustments to our men's basketball tournament schedule to accommodate Missouri's self-imposed postseason ban."
