DURHAM, N.C. (AP) — North Carolina coach Butch Davis says an NCAA probe into potential rule violations in his football program came "out of left field."

In his first public comments since the investigation began, Davis said Thursday the school is cooperating with the NCAA and that his program follows its rules.

A person familiar with the investigation says the NCAA is looking into whether two players received improper benefits from agents. Senior defensive tackle Marvin Austin and senior receiver Greg Little are the focus of the probe, the person told The Associated Press. The person spoke on condition of anonymity because the investigation is confidential.

The probe became public about a week ago after NCAA investigators visited the campus in Chapel Hill.
