Coming off their overtime win over the Patriots, the Broncos traveled to Qualcomm Stadium for their first of two matches with their AFC West division rivals, the San Diego Chargers. On the Broncos' opening drive, quarterback Brock Osweiler connected with wide receiver Demaryius Thomas on a 3-yard touchdown pass. The Chargers had a chance to get on the scoreboard midway through the first quarter, but placekicker Josh Lambo missed wide-right on a 48-yard field goal attempt. Toward the end of the first quarter, the Broncos added to the lead, when linebacker Danny Trevathan intercepted an errant pass by Chargers' quarterback Philip Rivers and returned it for a 25-yard touchdown. After forcing a Chargers' punt early in the second quarter, the Broncos marched down the field with a long drive that chewed up seven minutes, but had to settle for a 23-yard field goal by placekicker Brandon McManus that increased their lead to 17-0. The Chargers got on the scoreboard just after the two minute warning, with a 51-yard field goal by Lambo, which would be the final scoring play of the game by either team. In the third quarter, the Broncos' defense recovered two forced fumbles, while on offense, McManus missed wide right on a 52-yard field goal attempt and Osweiler threw an interception deep in Chargers' territory. In the fourth quarter, the Broncos' offense punted on all of their possessions (save the final kneel down), while their defense did not allow the Chargers' offense to advance past their own 47-yard line. NotesThe Broncos swept their division rivals on the road for the sixth time in seven seasons.
