Ted Miller Some notes to get you through the hours until Saturday. Many thanks to ESPN Stats & Information. Colorado leads the series with Arizona 13-1, including a 48-29 win last year. The Wildcats' only win in the series came in 1986. Arizona will be without quarterback Matt Scott, who suffered a concussion in the loss Saturday at UCLA. He will be replaced by B.J. Denker, a junior college transfer who joined the team this summer. The Buffaloes rank last in the Pac-12 in scoring offense, scoring defense, total offense and rushing defense.
