Arlington, TX – Baylor quarterback Robert Griffin III was replaced in the second half of Saturday's game against Texas Tech after taking a hit to the head late in the second quarter.
The Heisman Trophy hopeful was sliding feet-first near the right sideline at the end of a run when Texas Tech's Cornelius Douglas delivered a shoulder to the quarterback's helmet.
Douglas was whistled for a personal foul on the hit.
Griffin laid near-motionless on his back, but Baylor initially breathed a sigh of relief when he walked to the sideline, then came in after a play and scored on a three-yard run.
But Griffin was replaced by Nick Florence to start the third quarter after Baylor carried a 31-28 lead into the half.
Two years ago, Griffin sustained a season-ending knee injury in the third game of the 2009 season. On Saturday, he passed for 106 yards and a touchdown in the first half with 14 runs for 62 yards and a pair of scores.
