AUSTIN, Texas (AP) — Iowa State didn’t fret or panic while trailing Texas for nearly an entire game Friday.

Instead, the Cyclones looked like a program with championship DNA in the fourth quarter, despite not having won a conference title in more than 100 years.

Breece Hall scored on a 3-yard run with 1:25 remaining, and No. 15 Iowa State held off a last-minute drive by Sam Ehlinger and No. 20 Texas to remain in first place in the Big 12 with a 23-20 victory Friday.

“We don’t ever flinch,” Cyclones safety Greg Eisworth said. “That really is the truth.”

After Iowa State sacked Ehlinger on third down, Texas’ Cameron Dicker barely missed left with a 58-yard field goal attempt as time expired.

The Cyclones (7-2, 7-1) have almost locked up a spot in the Big 12 championship game for the first time with their second victory ever against Texas in Austin. Upstart Iowa State has beaten the blue blood Longhorns in consecutive seasons for the first time in 18 meetings.

“We always say it’s a five-star culture vs. five-star players,” Hall said. “We don’t always get the best players … We want to be in games like this where it comes down to physicality and hard work. So today, us and our defense, just kept playing and we came out with a great result.”

Hall gained 91 yards on 20 carries, his first game under 100 this season, but had 30 on the final 69-yard touchdown drive. Quarterback Brock Purdy connected with tight ends Charlie Kolar and Dylan Soehner for the other 39 yards.

“When we needed to make plays, and that’s what really good teams do, we made them,” coach Matt Campbell said.

Iowa State trailed 20-16 early in the fourth quarter after a bad two-play sequence for Texas (5-3, 4-3) helped the Cyclones get a field goal by Connor Assalley.

First, the Longhorns came up 3 yards short throwing the ball on a fake punt on fourth-and-8. Then Purdy found Kolar for 44 yards. A holding penalty by the Cyclones forced them to settle for the Assalley’s field goal to make it 20-16.

“The thinking on the fake punt was that we’d worked on it for two weeks and knew it was there,” Texas coach Tom Herman said. “They did a good job defending.”

Ehlinger was also were stopped inches short on a fourth-and-2 at the Iowa State 13 with 8:05 left in the fourth quarter when a field goal would have made it a seven-point game.

“The analytics said to go for it,” Herman said. “If you wind up converting and score a touchdown, you go up by 11. That’s two scores.”

Purdy completed 25 of 36 for 312 yards and one touchdown. Kolar made six receptions for 131.
