LUBBOCK – Baker Mayfield fell to the ground. He limped off the field with trainers by his side.
Fellow true freshman Davis Webb was called to take his place.
Webb's first play was a 10-yard completion to Jace Amaro. That play provided a spark for the Red Raider offense. After a couple of rushes from sophomore running back Deandre Washington and a couple of incomplete passes from Webb, Tech needed a fire.
Webb's spark became a 48-yard completion to Washington that lit a fire. Gasoline was poured on with a 15-yard personal foul against Tech.
Four plays later, Webb hit junior wide receiver Bradley Marquez in the back corner of the end zone with a 19-yard touchdown pass.
After a three-and-out by TCU, Ryan Bustin added a 37-yard field goal and the fans rushed the field.
The Texas Tech Red Raiders (3-0 (1-0)) won their Big 12 Confeence opener for the first time since 2008 over the No. 24 TCU Horned Frogs (1-2 (0-1)) 20-10.
Texas Tech Head Coach Kliff Kingsbury, who won his Big 12 Conference coaching debut, said Webb kept his head up during his time on the bench and was ready to step up.
"We needed a quarterback going in to make plays," Kingsbury said. "That's big time. Like I said, stay focused through all this and not get his head down, not pout, and just come out and compete. That's what you're looking for."
Webb finished the night 3-4 throwing for 77 yards and the game-winning touchdown. Mayfield, who Kingsbury said is walking around and feels well, tossed 216 yards and one touchdown. He finished 21-40, but was picked off three times.
Senior wide receiver Eric Ward was completely shut down with zero receptions.
Tech's defense was stout and recorded a first half shutout for the first time since 2009. TCU would eventually break-through and tie the game up in the second half.
Kingsbury said it was the best defensive performance of his career.
"It was the best defensive performance I've been a part of since I've been a coach," Kingsbury said. "We put them in bad spots all night offensively, and they kept stepping up and turning them over and getting stops against a talented offense with a really talented quarterback."
TCU sophomore quarterback Trevone Boykin threw two interceptions and failed to score a touchdown. The Horned Frogs lone touchdown came on a 17-yard run by B.J. Catalon to tie up the game 6:28 remaining.
The night was filled with penalties, reviews and missed opportunities against both sides. Officiating came into question at some points during the battle, but neither side commented during their press conferences.
Both sides missed a field goal and Tech had multiple opportunities to blast TCU away in the first quarter. The Horned Frogs also had a punt return for a touchdown called back because of an invalid fair catch.
Marquez, who caught the game-winning pass, took us through his version of the play.
"Just had a go called, and was able to get a beat on them and keep them on my back shoulder," Marquez said. "Just a beautiful ball by Davis Webb, and those kind of balls you don't drop."
The Red Raiders next game is September 21 when Texas State returns to Lubbock. Tech is unbeaten in the Kliff Kingsbury era and has knocked off the Red Raiders first ranked opponent in his coaching career.
Marquez said being 1-0 in conference play is not the main goal.
"It feels great," Marquez said. "That's not our main goal. We've got some more work to do, but it's definitely great to be in that position right now."
