The Pac-12 has reviewed film of the game between the University of Colorado and Colorado State from Friday’s Rocky Mountain Showdown and determined “there were no errors in application of the playing rules,” a Pac-12 spokesman told The Denver Post.

The announcement follows CU’s 17-3 victory against CSU in which the Rams were called for three offensive pass interference penalties that erased a touchdown and two red-zone opportunities. Video replays of the third call on the videoboard prompted CSU students seated at Sports Authority Field at Mile High to throw trash and bottles onto the field. The penalties also sparked a firestorm of online criticism among fans and media.

When asked for clarification on the offensive pass interference rules application, the Pac-12 provided the following statement:

“Pass interference is a judgment call and there were no errors in application of the playing rules during the Colorado State-Colorado game. Each play from each game is reviewed and each game official is graded on his or her performance. Downgraded performances may impact an official’s opportunity to work the postseason or receive future officiating assignments.”

The Pac-12 officiating crew for the game consisted of referee Chris Coyte, umpire Bryan Hay, linesman Darryl Johnson, line judge Jeff Robinson, back judge Nate Jones, field judge Steve Currie and side judge Jeff Dahle. The three offensive pass interference calls were flagged from the field judge position.

CSU receiver Olabisi Johnson was penalized for offensive pass interference in the first quarter, a call that negated a first-and-goal situation when the game was scoreless. After CU gained a 17-3 advantage, Rams wideouts Detrich Clark and Michael Gallup were both called for the same foul, erasing a touchdown and a possession inside the 20-yard line.

CSU coach Mike Bobo submitted reviews to the Pac-12 officiating office for 25 penalties called in the Showdown, but he wouldn’t blame the loss on three questionable flags. Said Bobo on Monday: “They made the calls. We moved on.”

CU coach Mike MacIntyre also addressed the officiating Friday night.

“Calls go either way all the time,” MacIntyre said. “I’ll watch it on film, and calls always go either way. There is no doubt about it. You never complain about officiating.”
