Hoping to rebound from their loss at New England, the Broncos traveled to Qualcomm Stadium for an AFC West duel with the San Diego Chargers on Monday Night Football. The Chargers jumped out to a 10-0 lead in the first quarter, with a 32-yard field goal by placekicker Nick Novak, followed by a 15-yard touchdown pass from quarterback Philip Rivers to tight end Antonio Gates. Both scores came off Broncos' miscues on special teams&#8212;the former occurred after Trindon Holliday muffed a punt return, while the latter occurred after Omar Bolden coughed up the football on a kickoff return. The Broncos were attempting to narrow the Chargers' lead midway through the second quarter, but wide receiver Eric Decker stumbled near the Chargers' 30-yard line when it appeared that he was headed to the end zone for an easy touchdown, after receiving a 55-yard pass from quarterback Peyton Manning. Three plays later, Manning threw an interception that was returned by Chargers' cornerback Quentin Jammer 80 yards for a touchdown. The Chargers increased their lead to 24-0 just before halftime, with Rivers connecting on an 11-yard touchdown pass to Gates. The Broncos then staged one of the most memorable comebacks in Monday Night Football history. On the opening drive of the second half, Manning led the Broncos on an 8-play, 85-yard drive, culminating with a 29-yard touchdown pass to wide receiver Demaryius Thomas. On the Chargers' next possession, Broncos' defensive end Elvis Dumervil forced a fumble off Rivers, and cornerback Tony Carter scooped up the football and returned it 65 yards for a touchdown. After the Broncos' defense forced a three-and-out, Manning hooked up with Decker on a 7-yard touchdown pass to pull the Broncos within 24-21 early in the fourth quarter. On the Chargers' next possession, Carter picked off Rivers, and four plays later, Manning tossed a 21-yard touchdown pass to wide receiver Brandon Stokley to give the Broncos a 28-24 lead with 9:09 remaining in the fourth quarter. The Chargers were attempting to rally, but Rivers was intercepted by cornerback Chris Harris, Jr. with 6:54 remaining. However, the Broncos were forced to punt seven plays later, giving the Chargers' offense the football with four minutes remaining. The Chargers once again tried to rally, but six plays later, Harris stepped in front of another Rivers' pass, returning an interception 46 yards for a touchdown, sealing the win for the Broncos.
