Auburn has told Bruce Pearl that if he does not cooperate with an internal investigation into its basketball program, he risks being fired, according to ESPN, which reported Wednesday that the Tigers coach has refused to speak with attorneys retained by the school.Those attorneys reportedly have not been able to determine whether Pearl, 57, has committed any NCAA violations because the FBI seized his computers and cellphones as part of the agency's own wide-ranging probe into corruption in college basketball. Auburn fired assistant coach Chuck Person on Wednesday, one day after he was indicted by a federal grand jury, as were three assistants at other schools.Person and the other coaches have been accused of accepting bribes and steering top prospects and their families to preferred financial advisers, business managers and agents. The FBI investigation resulted in the arrests of 10 people in September, including executives at Adidas, and it led to Louisville eventually firing longtime coach Rick Pitino.ESPN reported that Auburn has not given Pearl a deadline to begin cooperating with its investigation but that the school will make a decision on his continued employment "in the next week or two." Pearl is set to begin his fourth season at Auburn, after having been fired from Tennessee in 2011 for lying to NCAA investigators about a potential recruit."This is an ongoing investigation, and everybody is working to try to get our players certified and eligible," Pearl said after practice Wednesday. "And you guys know, from the very beginning, I'm not allowed to comment on the process." Asked about his job security, Pearl said, "I am not concerned. … I am no more concerned than anybody else."In related news, Pitino's lawyer said allegations in an indictment that implies the former Louisville coach was involved and aware of money payments to recruits are "false, misleading and defamatory."Steve B. Pence reiterated Thursday that Pitino had no knowledge of any payments. Pitino was fired last month amid the federal investigation.An indictment released Wednesday contains details of a meeting recorded by the FBI in July that indicates Pitino approved a plan to funnel $100,000 of Adidas money to Louisville recruit Brian Bowen's family. Louisville is an Adidas school. Pitino took a lie detector test in October and maintains he knew nothing about the plan. He has not been specifically named in the investigation, but he is widely believed to be the "Coach-2" who appears throughout the federal complaint.
