Watching Isaiah Oliver get helped off the field during the first half Saturday at Washington State was an unsettling feeling for Colorado football fans.
The star cornerback may not be out long, however.
On Monday, CU head coach Mike MacIntyre said Oliver, "was doing OK today. I think he'll be able to play, but we'll see. Hope he doesn't have any setbacks."
Oliver went down without contact on Washington State's first touchdown on Saturday. That left Tay Martin wide open for a 50-yard score down the middle of the field.
The Buffs have not indicated the specific injury for Oliver, but he was seen grabbing his lower right leg as trainers tended to him on the field.
Oliver wasn't the only Buff to leave Saturday's game with an injury.
Center Jonathan Huckins suffered a concussion late in the first half and did not return. He is currently going through concussion protocol and if he's unable to play, right guard Tim Lynott Jr. will move over to center, as he did for the second half Saturday. Lynott started two games at center earlier this year.
Reserve defensive lineman Timothy Coleman Jr., also left the game. Trainers worked on his left foot or ankle before he was carted to the locker room, and MacIntyre said he isn't sure if Coleman will play this week.
Despite losing Oliver, their best cornerback, early in the game, the Buffs pass defense was solid against one of the top quarterbacks in the country, Luke Falk.
For the night, Falk completed just 50 percent of his throws (17-for-34) for 197 yards. Falk, who is nearing the Pac-12's all-time passing record, has completed 70 percent of his throws in his career.
"(CU's secondary) disguised well," MacIntyre said. "I thought we had (Falk) guessing a little bit more than he had. We did a few things a little bit different for disguising and I thought they did a good job with that."
The Buffs nearly had about four interceptions, but could never hold onto the ball.
"If we had come up with four of them, it might have been a different football game," MacIntyre said.
Trey Udoffia and Dante Wigley both played well at corner against the Cougars.
"Both of those young men have kept improving," MacIntyre said.
