Auburn has reportedly hired a law firm to investigate allegations that a part-time academic support staff member took a final exam for at least one football player from the 2016 team, according to ESPN.

It was alleged that a mentor to an Auburn player took an online final exam for at least one football player, and then a tutor who worked with the mentor found out about it and reported it to the mentor’s supervisor. A source told ESPN’s Outside the Lines that the player told the tutor he had not taken the exam.

Here’s the full excerpt from the ESPN report:

A source told Outside the Lines that a mentor in Auburn’s Student-Athlete Support Services department took an online final exam for at least one football player. A tutor who worked with the mentor became aware of the alleged misconduct while reviewing a football player’s academic records in February, the source said, noticing that the player had received a perfect grade on a final exam only a few weeks into the course. The source said the player told the tutor he had not taken the exam.

After hearing that, the source said the tutor alerted the mentor’s supervisor. In August, the tutor who had reported the allegations was told her job wouldn’t be renewed, according to the source; the tutor then reported the issue to Auburn’s compliance director and the athletics department’s human resources office.

“It’s simply not true,” a statement from the Auburn athletic department said. “The person making the accusation is a part-time employee placed on administrative leave on Aug. 31 because of a dispute with a coworker. She is making claims not supported by facts, and based on what ESPN told us, she keeps changing her story. Neither she, her attorney nor our investigation have produced anything to support her claims.”

The athletic department confirmed with ESPN that it had indeed hired a law firm out of Birmingham.

The mentor apparently denied the tutor’s allegation to Outside the Lines.

“I’m shocked and surprised by that. It’s not true,” the mentor said. “I’ve never done anything with any of my interactions with my students that would be inappropriate.”
