The Arizona Wildcats trail Colorado by a score 10-7 after one quarter of play in Tucson.

The Wildcats stopped the Buffaloes on their first drive of the game, but a costly fumble inside their own 10-yard line led to seven easy points for Colorado. Arizona responded with an impressive touchdown drive that was capped off with a touchdown run from Ka'Deem Carey. With just seconds left in the first quarter, CU was stopped near the goal line and settled for a field goal to take a 10-7 lead.

Other than the early fumble, backup quarterback B.J. Denker has looked good for UA. Denker has completed four of his five pass attempts for 59 yards. Carey has carried the ball six times for 30 yards and the touchdown score.

Nick Hirschman, who was anointed Colorado's starter just hours before the game in place of Jordan Webb, is 5-for-5 with 50 passing yards so far. The 'Cats have been in a position to make big plays, but poor tackling has prevented them from getting off the field.

The second quarter is about to begin. Arizona has the ball at about midfield.
