The University of Missouri admitted NCAA violations in its men’s basketball program dating to 2011 and banned itself Wednesday from the postseason this year and vacated all 23 wins from the 2013-14 season.

The NCAA is still investigating and Missouri said it was working with the organization in hopes of limiting the punishment to its self-imposed sanctions, which includes the SEC tournament.

“We have faced this issue head-on,” athletic director Mack Rhoades said. “These are not decisions we took lightly. We really felt like it was the right thing to do, and it will help put us in position to move this program forward.”

Missouri was 23-12 in 2013-14, Frank Haith’s final season. Haith left for Tulsa not long after the school received a verbal notice of inquiry from the NCAA in April 2014.

The Tigers won just nine games last season under new coach Kim Anderson and are 8-8 this season, coming off the worst loss in Mizzou Arena history — a 94-61 setback to Arkansas on Tuesday that Anderson said made him “embarrassed.”
