The plot thickens in Oxford as the NCAA has reportedly expanded its investigation into the Ole Miss football program and possible violations that may have occurred under head coach Hugh Freeze.

According to Pat Forde of Yahoo Sports, enforcement agents from the NCAA have begun interviewing players at Auburn and Mississippi State, and potentially one other SEC West school, that were recruited by Ole Miss while in high school. These players have allegedly been granted immunity for any wrongdoings during their recruitment process in exchange for accurate and truthful statements to the NCAA’s representatives.

Both Ole Miss and the NCAA declined Forde’s request for comments.

Having already received a notice of allegations from the NCAA, Ole Miss self-imposed a number of penalties in May including probation, the reduction of scholarships and the reduction of its evaluation period of high school athletes, among other penalties.

Following Laremy Tunsil’s admission of receiving payments from a coach at Ole Miss to a room full of reporters immediately following being selected in the 2016 NFL Draft, the NCAA is expected to serve Ole Miss with an amended notice of allegations at some point in the near future.
