HOUSTON (AP) — Peyton Manning couldn’t score in more than a quarter of work in his preseason debut before Denver’s reserves rallied late to help the Broncos to a 14-10 win over the Houston Texans on Saturday night.

Manning led the team on four drives that all ended with punts before he was replaced by Brock Osweiler with 11 minutes left in the second quarter. The 39-year-old Manning was 8 of 14 for 52 yards.

Ryan Mallett, competing with Brian Hoyer to be Houston’s starting quarterback, opened the game on Saturday. He failed to move the offense, and the Texans punted on his two possessions. Hoyer was also unable to get into the end zone in his four drives.

Osweiler gave the Broncos a 7-0 lead on a 57-yard touchdown pass to Andre Caldwell early in the second quarter.

They were up 7-3 in the third quarter when Kourtnei Brown returned an interception of Osweiler 69 yards for the score. A 26-yard touchdown catch by Corbin Louks gave Denver a 14-10 lead.
