MANHATTAN, Kan. -- Oklahoma (No. 9 BCS, No. 11 AP) will chase another Big 12 title without Dominique Whaley.
The Sooners' leading rusher will miss the remainder of the season after fracturing his left ankle while blocking on the first play of Saturday's game against Kansas State. Whaley was taken off the field on a cart, but was walking around on crutches on the sideline in the second half.
The Sooners went on to beat the No. 10 Wildcats, 58-17.
Whaley will have surgery Sunday to have a pin inserted.
"I'm sure that'll be it for Dom for the year," Oklahoma coach Bob Stoops said. "Really sad for Dom. What a great young man. We'll miss him."
Whaley leads the Sooners with 627 yards rushing and nine touchdowns this season. Roy Finch and Brandon Williams will be first in line to replace him, and Brennan Clay will also get some snaps.
Finch ran for 73 yards and a touchdown on just nine carries against the Wildcats, and caught seven passes for 69 yards. Williams ran eight times for 28 yards, and fullback Trey Millard added a highlight of his own when he broke a 61-yard touchdown run in the closing minutes.
"Brandon and all the other guys will have to step up," Stoops said. "Roy did a great job. I thought all of them did. Those guys all played really well."
Whaley, who missed last week's loss to Texas Tech with an illness, has been a revelation in his first season with the Sooners. He transferred into the program from tiny Langston University, an NAIA program, and promptly took over the starting job as a walk-on.
He ran for 131 yards and four touchdowns in the season opener against Tulsa, and also eclipsed 100 yards rushing in lopsided wins over Ball State and Kansas.
Now, the junior from Lawton, Okla., will have to watch the rest of the season from the sideline.
"You don't want to lose a great player like Dom, because he does a lot of great things for us in the run game, the pass game," quarterback Landry Jones said. "But we've got some talent back there and I think we'll be all right."
