Denver scored its first points of the night on an eight-play drive in which quarterback Peyton Manning completed all four of his passes, including a 29-yard touchdown pass to wide receiver Demaryius Thomas.
The Broncos picked up a first down on the first play of the series on a 12-yard completion from Manning to tight end Joel Dreessen.
Denver followed the first down with a short run by running back Willis McGahee and another completion to Dreessen, this one for 19 yards another first down.
Two plays later, Manning completed a 14-yard pass to wide receiver Eric Decker to move the chains a third time.
On the following play, Manning once again connected with Dreessen on a 10-yard completion for a first down. From the Chargers 29-yard line, Denver followed a first-down run for no gain with the 29-yard touchdown pass from Manning to Thomas, who now has three touchdown catches on the season.
