The Pac-12 announced tonight it reprimanded and fined Arizona coach Sean Miller $25,000 for two post-game incidents after the Wildcats’ 66-64 Pac-12 Tournament loss to UCLA in Las Vegas.

The Pac-12 said Miller confronted an official on the floor immediately after the game and later “acted inappropriately” toward a staff member in the hallway of the MGM Grand Garden. Miller was called for a late technical foul that resulted in two UCLA free throws.

Miller had been warned about acting inappropriately toward officials after games.

"The conference has a formal system of evaluation and feedback in place for coaches to express concern about officiating," Pac-12 commissioner Larry Scott said.  "Coaches play a significant role in the overall officiating program and are expected to address concerns through the structure provided … Threatening, intimidating and unprofessional conduct will not be tolerated.

"Even in tense and trying moments following a game, we expect Pac-12 coaches to conduct themselves in a professional manner. Our coaches represent their teams, their universities and our conference.  We expect them to set an example for our student athletes and to meet the highest standard of sportsmanship and behavior on and off the court."

A UA spokesman said Sunday night that Miller would not comment on the fine and reprimand, though Miller referenced Friday's events during a brief news conference Sunday to discuss the Wildcats’ NCAA tournament placement.

After Friday's game, Miller had indirectly criticized officials for calling a double-dribble against Mark Lyons because he believed a UCLA player touched the ball, and then criticized himself for picking up a technical foul when he argued the point during the game.

 “You get into situations and circumstances and you learn a lot,” Miller said. “This week was a learning experience and what it tells me as the coach at Arizona is that we have each other, that our players and their development and their opportunity is by far the thing that matters the most, especially to me. To never lose sight that it’s about one thing: The University of Arizona.”
