The Houston Texans fell, 31-3, at Indianapolis after allowing 21 unanswered points and committing three turnovers in the second half.

"Turnovers, penalties, unforced errors, that's bad football, and those are ways that keep you getting beat," RB Mark Ingram II said.

The Texans finished with 353 yards of offense (229 passing, 124 rushing) despite being without starters Laremy Tunsil and Justin Britt on the offensive line. Geron Christian Sr. and Justin McCray stepped in for Tunsil and Britt, respectively.

QB Davis Mills completed 29-of-43 passes for 243 yards and two interceptions, including one on the Texans' first possession of the second half. That pick came after Houston's defense forced a three-and-out on the Colts' opening series after the intermission.

"I thought the first half he played well, just like he had played the last game and second half the turnover basically flipped the whole game around for us with that INT," Head Coach David Culley said. "And then I thought after he came back after that, he settled down and he did some things that made the interception at the end really no big deal, but again, I just go back to critical mistakes that we're making at critical times and that INT at that time was a big momentum changer during the game."

WR Brandin Cooks caught nine passes for 89 yards and WR Nico Collins added four receptions for 44 yards in his return from Injured Reserve. Ingram led the team with 18 carries for 73 yards. RB Phillip Lindsay added seven carries for 39 yards.

Second-year DL Jonathan Greenard had two sacks and finished with a team-high six tackles (five solo), three quarterback hits and two tackles for loss. Greenard now has four sacks in four games.

Carson Wentz completed 11-of-20 for 223 yards and two touchdowns, while RB Jonathan Taylor rushed for 145 yards and two scores. Colts WR T.Y. Hilton caught four passes for 80 yards in his 2021 debut.

"A lot of those plays that I think we gave up from a big play standpoint, but simply because that we weren't reading our keys, we weren't where we needed to be on those particular plays," Culley said. " And when you do that with a good running back, big plays happen."

The Colts took a 7-0 lead after Wentz threw a 51-yard touchdown pass to WR Parris Campbell in the first quarter.

K Ka'imi Fairbairn's 31-yard field goal gave Houston its only points of the game, to cap off a 13-play, 62-yard scoring drive in the second quarter.

At halftime, Mills was 17-of-23 for 139 yards and the Texans put up 181 yards of offense but trailed 10-3.

On the Colts' first possession of the second half, Greenard ended the drive with a sack, but the defense would be back on the field quickly. LB Darius Leonard picked off Mills' pass, intended for Collins, on the first play of the Texans' following series. Two plays later, Wentz threw his second touchdown of the day. TE Mo Alie-Cox caught a 28-yard touchdown reception to give the Colts a 17-3 lead early in the third quarter.

"We got the stop, the next series we have the ball, we throw an interception, and then they get a big play, and then it snowballed from there," Culley said.

The Colts scored again on their next possession after an 83-yard run by Taylor, which kickstarted the drive. Wentz handed off to Taylor three more times, who scored on a four-yard touchdown run to finish the drive. The Texans trailed 24-3 with 6:37 left in the third quarter.

RB David Johnson's fumble, recovered by Leonard, led to another Taylor touchdown. The Colts took over at their own 37-yard line, and Taylor scored on an 11-yard run, his second rushing touchdown of the game. Indianapolis took a 31-3 lead with 4:47 left in the game.

Lindsay added a 35-yard run on the next Texans' possession, but a second interception thrown by Mills would end the drive in Colts' territory.

With the loss, the Texans fall to 1-5 on the season and will next travel to Arizona to face the Cardinals in Week 7 at State Farm Stadium next Sunday.
