The University of Mississippi athletic program is under investigation by the NCAA for potential rules violations in multiple sports.

Athletic director Ross Bjork confirmed to Yahoo Sports on Wednesday that Ole Miss “is working with the NCAA” in an ongoing investigation. Bjork said the school has not received a Notice of Allegations from the NCAA, nor does it have a date set for a hearing before the NCAA Committee on Infractions. He declined further comment.

Multiple sources told Yahoo Sports the Mississippi football and women’s basketball programs are subjects of the investigation. One source with knowledge of the probe said the bulk of the potential violations relate to women’s basketball. The source said the current football staff of head coach Hugh Freeze is not believed to be implicated in any major violations, and that much of the football inquiry dates back to actions by a previous Ole Miss staff. Freeze is in his third year at the school. The source said there have been no new allegations, all NCAA interviews have completed and the school is waiting for the NCAA Department of Enforcement's next step.

Bjork fired women’s basketball coach Adrian Wiggins and two of his assistants in October 2012 after alleged wrongdoing came to light. The football investigation also has been ongoing for more than a year, multiple sources said.
