Receiver Paul Richardson (sprained ankle) and tailback Michael Adkins (concussion) were both injured Saturday. Both were listed as being day-to-day, and according to CU, that status did not change on Sunday.
Richardson, who caught seven passes for 132 yards on the night, was injured late in Saturday's loss.
"Somebody rolled on top of me or I rolled my ankle," he said. "I don't know what happened. I'll get it checked out."
Richardson tweeted "Boot Life." with a photo of a walking boot on Sunday evening.
Adkins led CU with 54 rushing yards on 16 carries. He has a team-leading 369 yards this season.
No issues with effort
Although the results in Pac-12 play have been ugly, the players and coaches have liked the effort put out by the Buffaloes.
"Coach (Mike) MacIntyre was telling us how much he loved our effort," offensive lineman Alex Kelley said. "The game kind of got away from us, but we never took our foot off the pedal. We just kept going."
Wide receiver Nelson Spruce said that CU's effort against the Wildcats was encouraging.
"That is something we can build on," Spruce said. "As long as we have that, then we can keep building as a team."
Saturday was the first time in nearly two years that CU did not give up a sack. CU quarterbacks had been sacked at least once in 20 consecutive games, dating back to Arizona's previous trip to Folsom Field, in 2011. Those two games against Arizona are the only games in the last 30 that CU avoided sacks. ... CU converted 41 percent (7-for-17) of its third-down opportunities. The Buffs came in ranking 110th nationally, at 31 percent. ... In the Pac-12, Oregon (8-0), Stanford (7-1) and Oregon State (6-2) are all bowl eligible already. Arizona State (5-2), Arizona (5-2), UCLA (5-2), USC (5-3) and Washington (5-3) are just a win away from eligibility. Utah (4-4) and Washington State (4-4) are within reach, too.
