Coach Mike MacIntyre said Powell and Frazier each had repair work done on meniscus injuries. Powell is already on the mend and should be able to participate in the second half of spring drills, if not sooner. Frazier just had surgery this week and might miss all of spring practices.
The first of 15 practices over nearly six weeks comes Friday morning with another scheduled for Saturday. The Buffs will conduct half of spring practice before spring break and half after with the spring game scheduled for April 12 and a final practice April 14.
Powell has been a regular starter at tailback the past two years and led the Buffs in rushing in each of those seasons. He finished the 2013 season with 562 rushing yards and is expected to factor heavily in the offense in 2014.
Frazier was signed in the 2013 recruiting class as a linebacker. He was moved to fullback last season and MacIntyre said one of the players he was looking forward to working with most this spring was Frazier. MacIntyre said Frazier looked promising on scout teams at times last fall.
"That's a big blow to us cause he was going to work hard at fullback and H-back. He's a big body," MacIntyre said. "We won't be able to see him do stuff in the spring. He's going to have to really do stuff in the fall.
It's a shame.
"I'm hoping he can be back the last part of spring, but we'll see."
