Pulling off an upset against the highly-ranked Oklahoma Sooners will likely need to happen for the Texas Longhorns without the services of two offensive starters.

Kirk Bohls of the Ausitn American-Statesman reported on Wednesday that team sources were not hopeful that senior wide reciever Daje Johnson (head) and junior offensive tackle Kent Perkins (knee) will be able to play on Saturday.

Johnson left the TCU game after the second offensive play when he fumbled after taking a hard hit from several TCU defenders. On Monday, head coach Charlie Strong said that Johnson didn't know where he was after the hit and play caller Jay Norvell added on Tuesday that Johnson is currently day-to-day and "not totally back yet."

However, count redshirt freshman quarterback Jerrod Heard as one unconcerned about the effects of missing Johnson.

"We've got a lot of talented short guys like Daje," he said.

However, players like junior Jacorey Warrick and freshman Ryan Newsome are hardly proven commodities -- the next big play for Warrick will be his first at Texas and Newsome hasn't had many opportunities yet this season.

As for Perkins, he missed the entire TCU game last week and didn't even travel with the team to Fort Worth. He's now been listed as day-to-day since his injury. The offense cratered after he took a helmet to his knee against Oklahoma State and the pass protection from senior Marcus Hutchins didn't improve much with a full week to prepare.

The good news is that the team expects senior defensive end Shiro Davis to return this week after he missed the game against the Horned Frogs. Freshman linebacker Breckyn Hager's injury was also not as serious as it initially appeared -- though he'll likely miss a few games, he suffered a high ankle sprain against TCU.
