Freshman running back Roy Finch could miss the first half of the season for No. 7 Oklahoma with an ankle injury.
Coach Bob Stoops said after practice Wednesday night that Finch has a hairline fracture and such an injury usually takes about six to eight weeks to heal. Stoops said he still expects Finch to play this season.
Finch, from Niceville High School in Florida, was one of the Sooners' reserves behind starter DeMarco Murray before being hurt in a scrimmage last week. Stoops said he's now in a cast and getting around on crutches.
"He's got a good attitude and, you know, Roy, he'll do well. He'll be back and we expect him to play," Stoops said. "They don't foresee any complications with that, so we'll see. There's no dislocation or anything, so hopefully it goes smooth."
The Sooners also won't have backup Mossis Madu for their season opener Sept. 4 against Utah State. He has been suspended after pleading guilty to a misdemeanor charge of driving under the influence of alcohol.
Stoops also said defensive end Frank Alexander was "probable" for the opener with a sprained ankle.
