The Pac-12 claimed Kentucky fans harassed the Music City Bowl officiating crew, particularly referee Chris Cotye, for days after the game, according to ESPN's Kyle Bonagura.
Cotye, a Pac-12 referee, was in charge of the Dec. 29 contest that saw Northwestern defeat Kentucky 24-23, after Wildcats star running back Benny Snell was controversially ejected.
Kentucky fans allegedly sent numerous threats to Cotye's cell and office phones, and to his commercial real estate association.

Kentucky athletic director Mitch Barnhart was very critical of Cotye and his crew in a letter to the Pac-12's vice president of officials sent in early January, questioning Snell's ejection and the handling of an injury to quarterback Stephen Johnson.
The Pac-12 supported Cotye's decision to boot Snell from the game afterward.
