The Broncos have cut San Diego’s lead to 10 points on a defensive touchdown by cornerback Tony Carter.
San Diego moved down the field from its own 15-yard line to Denver’s 33-yard line and faced third down.
The Chargers advanced the ball with runs by running back Ryan Mathews mixed in with short completions by quarterback Philip Rivers to wide receivers Malcolm Floyd and Eddie Royal.
The drive halted on the following play when a sack by defensive end Elvis Dumervil knocked the ball out of the hands of Rivers and was scooped up by Carter, who raced 65 yards untouched into the end zone.
The sack gives Dumervil four on the season and the play also marked the first touchdown of Carter’s career. The 65-yard return is the sixth-longest defensive touchdown in team history and the third-longest in the NFL this season.
