Ka’Deem Carey rushed for four touchdowns and Arizona extended Colorado’s Pac-12 losing streak to a dozen games with a 44-20 win over the Buffaloes at CU’s Homecoming.

Carey, the nation’s leading rusher, ran for 119 yards on 23 carries. But it was his quarterback, B.J. Denker, who surprised the Buffs on the ground with a career-best 192 yards on 15 keepers.

Colorado was held to 349 yards of total offense, with freshman quarterback Sefo Liufau going 17-for-32 for 212 yards, a touchdown and an interception. No Colorado runner had more than 54 yards, while Paul Richardson had seven catches for 132 yards, including a 75-yard touchdown reception in the first quarter.
