Passage: 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 from 26 and 40 yards out narrowed the Broncos lead. However, the Broncos struck back, with Manning connecting on three touchdown passes to wide receiver Demaryius Thomas 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.
