FORT WORTH —Johnny Manziel, who won the 2012 Heisman Trophy while Kliff Kingsbury was his quarterbacks coach at Texas A&M, attended Thursday night's Texas Tech-TCU game. Tech graduate Erik Burkhardt, who has also been an agent for Manziel and Kingsbury, was in attendance as well.

Kingsbury said he knew Manziel was coming.

Manziel plays for the Montreal Alouettes and had some down time between the Alouettes' last game, a 12-6 home victory against Calgary on Monday, and their next game Oct. 20 at Toronto.

"I'd been begging him since 2013 to make it to a game," Kingsbury said, "and he had a bye week, so it was good to see him."

Manziel and Burkhardt visited with Kingsbury before the game and spent time on the Tech sideline.

"I just told him thanks for finally coming. It's only been six years," Kingsbury said jokingly about his former pupil at Texas A&M "But he's doing well up there. I'm really proud of the direction his life's going, and I owe him a lot."

Shuffle up front

Two of Texas Tech's longest active games-started streaks went by the wayside Thursday night at TCU.

Center Paul Stawarz, who had started 26 games in a row, was out with a concussion. Left guard Madison Akamnonu didn't start for the first time in 19 games, though the junior from Arlington Bowie was in uniform.

Junior Bailey Smith and senior Jacob Hines replaced them, Smith making his first start since two years ago at Iowa State and Hines making his first start since last season.

Kingsbury indicated Akamnonu could have played.

"We just thought Hines has been practicing well and let him go," Kingsbury said.

The line got shuffled more when left tackle Travis Bruffy went down in the second quarter with an apparent leg injury. Bruffy's started 15 games, and when he went out, redshirt freshman Dawson Deaton took his spot. Deaton allowed two sacks.

Step forward

Tech quarterback Alan Bowman warmed up in full uniform, but changed back into street clothes before the game and watched from the sideline. Though he didn't play, Bowman's vigorous warmup was a good sign after he spent four nights in the hospital with a partially collapsed lung suffered in the previous game.

"We're going to be smart, and hopefully we'll have an answer by Sunday," on his availability next week, Kingsbury said. "He wasn't ready to go. We just wanted to put him through (warmup) and keep him locked in."

McLane Carter also suited up and played for the first time since the season opener, when he suffered a high-ankle sprain. Carter started the second half and played one series, but Kingsbury said the sore ankle was still a factor.

Brief return

Tech flanker T.J. Vasher, who missed the previous game with a sprained right knee, was back in the starting lineup, but his return was short-lived. Vasher came out of the game on the first offensive series and was attended to by athletic trainers then and during the next defensive series.

At that point, he was taken to the locker room and did not return to the game.

Vasher's absence led to the most extended playing time yet for Dalton Rigdon, a redshirt freshman from Perryton.

Never too late

Tech wide receiver Antoine Wesley had no catches at halftime, but made an impact in the second half. On the same series, Wesley converted a third-and-8 from the Tech 4 with a 9-yard catch and converted a second-and 15 from the Tech 27 with a 16-yard reception.

After TCU went ahead 14-10, Wesley caught a 57-yard pass to the TCU 13, though that drive stalled and Tech had to punt.

Wesley nearly pulled off another key reception on a deep sideline throw, but couldn't quite stay in bounds as he caught the pass.

Turnover at last

TCU drove from its own 19-yard line to the Tech 8 on its second series before linebacker Jordyn Brooks intercepted a Shawn Robinson pass into the end zone. The third time was the charm for the Red Raiders, who twice on the series failed to recover Horned Frogs fumbles.

When a backward pass to wide receiver Jalen Reagor got loose, there were four Tech players and two TCU players in the vicinity, but the bounce went to the Horned Frogs. Later, Robinson fumbled deep in Tech territory, but the Frogs recovered again.

The sequence continued a bad trend for Robinson, who came into the game having thrown six interceptions for the season and having lost three fumbles in the previous three games.

In brief

Backup LB Christian Taylor missed the game with a broken hand. ... Seth Collins made his first start at H inside receiver, and RB Tre King made his first start of the season. Collins switched to the other inside receiver position after backing up Y inside receiver Ja'Deion High for the first five games. King carried 10 times for 60 yards. ... QB Jett Duffey led Tech in rushing for third time in six games, finishing with 83 yards against TCU after rushing for 81 yards against Lamar and 86 against West Virginia.
