TCU lost to Texas Tech 20-10 Thursday night in its first game in Big 12 Conference play.

TCU trailed Texas Tech at halftime 10-0, and the Horned Frog offense looked lost for most of the first half.

Trevone Boykin, making his first start of the season, went 8-10 passing for 67 yards and an interception.

The run game for TCU also had troubles. Five players carried the ball for the Frogs, but the team had only 66 rushing yards. Texas Tech’s defense held TCU scoreless in the first half, which is the first time the Red Raiders have done that in Big 12 play since 2009.

TCU’s defense gave up some big plays to the Raiders early, including a 50-yard touchdown pass to WR Jakeem Grant from quarterback Baker Mayfield on Texas Tech’s first drive.

The Raiders then scored again on a 39-yard field goal to make the score 10-0. However, the defense settled in after that, intercepting Mayfield twice to end promising drives.

The game included some questionable calls by the officiating crew that affected the course of the game.

A punt return for a touchdown was nullified because the referees said Brandon Carter called for a fair catch on the play. They also ruled that a runner for Texas Tech was down by contact when it appeared he had fumbled the ball, which would have given the Frogs the ball with under three minutes left and a chance to tie the game.

Penalties also hurt TCU. The Frogs committed 13 penalties for 115 years, consistently putting the offense at a disadvantage on early downs.

The Horned Frogs' offense was inconsistent, scoring only ten points and failing to sustain drives for much of the game. Boykin made some impressive plays, but threw two interceptions and had only 194 yards passing.

The offensive woes overshadowed an impressive performance by TCU's defense, which held the Red Raiders scoreless for much of the game after giving up 10 points in the first quarter.
