Davis Mills got his first taste of NFL game action in the Houston Texans preseason opener at Lambeau Field. After Tyrod Taylor exited the game following the first offensive series, Mills entered the game and remained under center until 10:08 remaining in the third quarter. The rookie quarterback orchestrated back-to-back scoring drives, completing 11-of-22 for 112 yard and one interception in his debut.

"With him, if something bad happens, he comes back with that next play mentality," head coach David Culley said. "I think he held up very well from start to the finish when he was in there. He did things that we were trying to get him to do and when things weren't right, the positive thing about him was that he comes back and those things don't bother him."

Mills led the offense on two scoring drives before halftime. In the second quarter, Mills found running back Scottie Phillips for a 10-yard catch-and-run. Two plays later, Mills threw a deep 24-yard pass to rookie receiver Nico Collins to set up first-and-goal. Phillips scored on a five-yard touchdown run to cap off a six-play, 42-yard drive. The Texans took a 10-7 lead with 9:14 left in the second quarter.

"I think he went out there and competed," Taylor said. "He went out there and he made some plays in the passing game, got guys in the right spots and in the running game as well too, something to build from." 

On the Texans' next possession, Mills had his longest drive of the game, a 17-play, 68-yard series, and converted five first downs with completions to rookie tight end Brevin Jordan, Keke Coutee, Chris Conley and Anthony Miller. Ka'imi Fairbairn kicked a 25-yard field goal to give the Texans a 13-7 lead.

However, Mills' first NFL interception took place just two plays later. On the Packers next drive, the Texans defense forced a takeaway on the first play. Texans defensive lineman Jonathan Greenard's strip sack on Jordan Love gave Houston possession at the Green Bay 17-yard line. Mills threw a pass, intended for Kahale Warring, but it was picked off by Packers cornerback Kabion Ento at the Green Bay four-yard line.

Mills played one more series to open the second half before Jeff Driskel entered the game in relief in the third quarter.

"I noticed poise," Conley said of Mills. "As a quarterback, you got to be able to have a short memory and snap back quickly even when you make mistakes, highs, lows, and I think he did a really good job of that and he's continuing to improve."
