DALLAS — Oklahoma quarterback Dillon Gabriel, who missed last year’s Red River Rivalry game with a concussion from the week prior, stamped his place in the game’s history books as he hit Nic Anderson in the back corner of the end zone with 15 seconds left to play to lift the Sooners to a thrilling come-from-behind 34-30 win over the Texas Longhorns on Saturday at the Cotton Bowl. It marked the last time the two rivals will play as Big 12 Conference members as each will join the Southeastern Conference next season.
