MISSOULA, Mont. (AP) — The University of Montana says the NCAA is investigating possible violations involving its football program.

The NCAA notified UM President Royce Engstrom about the investigation on Jan. 30. The letter does not say why the program is being investigated and Engstrom said Wednesday the NCAA has not told him the reason.

As part of UM's investigation last winter into how it handles reported sexual assaults, the university's legal counsel cautioned employees about referring student-athletes to outside attorneys. David Aronofsky said such referrals are legal, but could appear to violate NCAA rules about seeking or receiving benefits in the form of free or discounted legal fees.

UM Vice President Jim Foley told the Missoulian he met two football players at an attorney's office on a Sunday after they were arrested for disorderly conduct by police who were breaking up a party last fall.
