Coming off their win over the Redskins and subsequent bye week, the Broncos traveled to Qualcomm Stadium for an AFC West duel with the San Diego Chargers. A 74-yard touchdown pass from quarterback Peyton Manning to tight end Julius Thomas in the first quarter gave the Broncos the early lead. Two second-quarter field goals by Chargers' placekicker Nick Novak &#8212; from 26 and 40 yards out &#8212; narrowed the Broncos lead. However, the Broncos struck back, with Manning connecting on three touchdown passes to wide receiver Demaryius Thomas &#8212; an 11-yarder, a 7-yarder just before halftime and a 34-yarder on the opening possession of the second half, which increased the Broncos' lead to 28-6. On the Broncos' next possession, Chargers' linebacker Tourek Williams forced a fumble off Manning deep in Broncos' territory, and the Chargers immediately capitalized two plays later, with quarterback Philip Rivers throwing a 7-yard touchdown pass to running back Danny Woodhead. The Chargers further narrowed the Broncos' lead early in the fourth quarter, with running back Ryan Mathews rushing for a 1-yard touchdown to pull to within 28-20 with 10:44 remaining in the fourth quarter. The Chargers' defense forced a punt on the Broncos' next possession, and with 6:43 left in the game, the Chargers tried to rally, however, the Broncos' defense forced a Chargers' punt with 3:37 remaining, and the Broncos' offense subsequently ran out the clock..
