Hoping to rebound from their loss to the Chargers, the Broncos traveled to Reliant Stadium for an AFC match with the Houston Texans. The two teams traded field goals in the first quarter, with a 32-yarder by Broncos' placekicker Matt Prater and a 45-yarder by Texans' placekicker Randy Bullock. The Broncos grabbed the lead early in the second quarter, with a 36-yard touchdown pass from quarterback Peyton Manning to wide receiver Demaryius Thomas. A 35-yard field goal by Bullock narrowed the Broncos' lead, but the Broncos increased it with two field goals from Prater in the final minute of the first half &#8212; a 25-yarder and a 44-yarder. A 15-yard touchdown pass from Texans' quarterback Matt Schaub to wide receiver Keshawn Martin was the only scoring play of the third quarter, which narrowed the Broncos' lead to 16-13. After Broncos' safety Mike Adams intercepted Schaub early in the fourth quarter, the Broncos subsequently pulled away, with Manning throwing two touchdown passes to wide receiver Eric Decker &#8212; a 10-yarder and a 20-yarder. Later in the fourth quarter, Manning threw his 51st touchdown pass of the season &#8212; a 25-yarder to tight end Julius Thomas, in which Manning set a new NFL record for touchdown passes in a single season. With the win, coupled with the Kansas City Chiefs' loss to the Indianapolis Colts, the Broncos clinched the AFC West division title. This was the 13th division title in the Broncos' franchise history, surpassing the Oakland Raiders for the all-time lead in AFC West championships since the 1970 AFL-NFL merger. It also marked the first time in franchise history that the Broncos have clinched three consecutive AFC West division titles.
