Third quarter: Texas Tech 29, Texas 19

Posted by ESPN.com's Tim Griffin

LUBBOCK, Texas -- Texas quarterback Colt McCoy is in a position where he can cement the Heisman Trophy and help his team keep its No. 1 ranking.

But it's not going to be easy as he'll be facing his biggest challenge this season. Tech has done a good job of bottling up McCoy through three quarters with surprising pressure. The Red Raiders have dropped him for four sacks and sent him to the sidelines after one possession earlier in the third quarter.

McCoy hooked up with Malcolm Williams on a 37-yard touchdown pass on the next-to-last play of the third quarter to pull the Longhorns within 29-19. A pass interference play on the two-point conversion was overruled when the ball was tipped at the line of scrimmage by Brandon Williams.

That was the only offensive touchdown of the third quarter as both defenses rose up. Texas Tech safety Daniel Charbonnet's 18-yard interception return for a touchdown accounted for the only Red Raider points of the quarter.

Texas' defense did a good job containing Tech's offense, allowing them only 73 yards in the third quarter. The Red Raiders struggled with poor field position and some uncharacteristic conservatism as coach Mike Leach has chosen to run the ball extensively close to his own end zone.

McCoy's Heisman hopes and Texas' BCS top positioning will be depending on the next 15 minutes. It should be interesting.
