Peterson sits out practice with ankle injury

NORMAN, Okla. -- Adrian Peterson sat out Oklahoma's practice
Monday because of a right ankle injury, with Sooners coach Bob
Stoops saying he hopes the star running back will be able to play
Saturday against No. 2 Texas.

Peterson, who finished second in the Heisman Trophy balloting
last season, aggravated the injury in the second quarter of
Oklahoma's 43-21 win against Kansas State on Saturday. He wore a
boot Monday at practice.

"It's better than it was [Sunday]. It's improved," Stoops
said. "They're probably going to take that boot off [Tuesday].
He'll probably be ready to go, hopefully by Wednesday."

Peterson left two other games with apparent foot injuries this
season, but returned on both occasions. Stoops has said the injury
was similar to the earlier ones, and he thought Peterson could have
played in the second half if necessary. However, the Sooners were
ahead 26-0.

In Peterson's absence, Oklahoma ran for 156 yards in the second
half against Kansas State.

Peterson, who ran for 225 yards in Oklahoma's 12-0 win against
Texas last year, was not allowed to speak to reporters after
practice Monday.

Earlier in the day, Texas coach Mack Brown said he expected
Peterson to participate in the game at the Cotton Bowl in Dallas.

"Adrian is a great player and he is a tough guy and he is from
the state of Texas and he will be full speed and ready to go on
Saturday," Brown said. "I am sure we will see the best out of

Oklahoma expects to be without starting center Chris Chester,
who injured his right knee against K-State, and starting tackle
Branndon Braxton's status is uncertain. Offensive line coach Kevin
Wilson said Braxton has a sore Achilles tendon.

"He didn't do much today," Wilson said Monday. "He didn't
look good. He's cleared by the trainers. He's cleared to go."

Wilson said he expected senior Chris Bush, who has experience at
center, to move over a spot and replace Chester in the starting
lineup while redshirt freshman J.D. Quinn and freshman Jon Cooper
contribute at center and guard.

The Sooners also have the option of moving senior Davin Joseph
and freshman George "Duke" Robinson between the guard and tackle
positions and feel comfortable with many of their linemen at
different positions.

"I feel like we've got eight guys we can count on, and
typically that's what every NFL team has live in every game,"
Wilson said. "With those eight guys, we've got four tackles, we've
got five guards and we've got three centers in that combination of
eight guys. We've got some combinations."
