AUSTIN (AP)  The Texas Longhorns are taking a ghost from Oklahoma's past into this weekend's Red River Rivalry game.

First-year offensive coordinator Bryan Harsin was calling the plays for Boise State when the Broncos knocked off the Sooners in the 2007 Fiesta Bowl with trick plays in a wild finish.

Harsin replaced Greg Davis, who had run the Texas offense for 13 years but resigned after Texas had a losing season in 2010. The Longhorns have already used several trick plays to score touchdowns this season. The message to the Sooners' defense is to expect just about anything.

Third-ranked Oklahoma (4-0, 1-0 Big 12) and No. 11 Texas (4-0,1-0) meet Saturday in the Cotton Bowl in Dallas.

You can listen to the game locally on 105.3 The Fan and 1080 KRLD  Saturday at 11:00 a.m.
