New Mexico has hired an outside investigator to look into alleged player mistreatment by football coach Bob Davie, according to the New Mexico Fishbowl.

Multiple sources told the outlet that the university is investigating claims of player mistreatment. In addition, it is looking into whether the school’s student-athlete drug-testing program has been compromised.

The investigation was launched in recent months after exit interviews conducted with departing athletes this past spring.

The outside investigator has not been named publicly, nor has the reason for its initiation been revealed.

“I can confirm there is an investigation underway in Athletics,” New Mexico spokesperson Cinnamon Blair told the NM Fishbowl. “We are not going to comment on the details or the individuals involved until the investigation is complete.”

Davie took over the football program after the disastrous tenure of Mike Locksley. Under Locksley, the Lobos won just two games in three years before he was fired following an 0-4 start in 2011.

Though Davie got off to a slow start, never winning more than four games in his first three seasons, the program has steadily improved. In 2015, the Lobos went 7-6. And last season, they finished 9-4 with a win in the New Mexico Bowl.

Prior to his time at New Mexico, Davie served as Notre Dame’s coach from 1997-2001, posting a 35-25 overall record.

New Mexico is 1-1 this season and plays at Boise State on Thursday at 7 p.m. in a nationally televised game on ESPN.
