MANKATO - Letroy Guion's transition to nose tackle shouldn't be delayed by more than a week, Vikings coach Leslie Frazier said Sunday morning as the team returned to practice following Friday night's 17-6 preseason-opening loss at San Francisco.
Guion, the former backup to under tackle Kevin Williams, sprained the posterior cruciate ligament (PCL) in his right knee in the first quarter. He sat out Sunday's light indoor practice and will be sidelined through Friday's second preseason game against the Buffalo Bills at Mall of America Field.
"You don't really want him to miss a whole lot of time, because he's a guy that we are counting on to really be a factor for us at that position, a major factor," Frazier said. "We should get him back for the third preseason game."
Guion said he hurt the knee when he banged it on the turf at Candlestick Park.
"It didn't seem that bad at first," he said. "But I went a couple of plays, and it started getting stiff on me."
Guion is trying to overcome the perception that he's undersized for the position that big Pat Williams once locked down so well.
"It's been a great adjustment," he said. "I feel like I'm doing good. Running around, playing double teams and doing everything I need to do to put myself in a great position. I can do a lot of great things in the 'A' gap. Quickness, speed, power. I can hold it down in the 'A' gap."
Brinkley struggled Jasper Brinkley, whom the Vikings have high expectations for at middle linebacker, played Friday night like a guy who hadn't seen live game action in 355 days.
