MISSOULA — University of Montana Grizzlies starting offensive tackle Trevor Poole was arrested after allegedly buying drugs early Sunday morning at the Disco Bloodbath III party.

A man later identified as Poole “engaged in a ‘hand to hand transaction’ involving the exchange of cash for a plastic baggie,” according to charging documents filed Monday by Deputy Missoula County Attorney Shaun Donovan.

Poole admitted to officers that he had two “molly” pills in his pocket, Donovan’s affidavit said. Molly is a street name for a club drug.

“He also admitted purchasing the pills that night from a male who offered to sell him the drug,” the affidavit said.

Poole, 20, a redshirt sophomore from Spokane, faces a felony charge of controlled possession of dangerous drugs. He was booked into the jail just before 4:15 a.m. Sunday and held on a suggested bail of $50,000.

"That calls for immediate, indefinite dismissal," UM athletic director Kent Haslam said Sunday evening.

Haslam said Grizzlies head coach Mick Delaney called him Sunday morning to tell him about the arrest. Haslam in turn immediately contacted UM President Royce Engstrom.

Poole's situation falls under a Category 1 violation of UM's Student Athlete Code of Conduct, which applies to someone charged with a felony when it's reasonable to believe the person committed the act.

UM's Athletic Conduct Team, comprising the athletic director, senior associate athletic director and the faculty athletic representative, was convened and made the decision to suspend Poole, Haslam said.

Poole was arrested at a large party that had been heavily advertised in advance, he said.

Donovan’s affidavit in Poole’s case described the party as a “rave.”

Two other people also face felony drug charges as a result of arrests at the party. Matthew Tyler Rardin and Kyle Don Nelson, along with Poole, all were to appear Monday in Missoula County Justice Court.
