The Chargers scored took a 10-0 lead, with quarterback Philip Rivers connecting on a 5-yard touchdown pass to tight end Hunter Henry, followed in the second quarter by a 37-yard field goal by placekicker Josh Lambo. Chargers' return specialist Travis Benjamin fumbled a punt return at the Chargers' 11-yard line, however, the Broncos did not gain any yardage, and were forced to settle for a 29-yard field goal by placekicker Brandon McManus. Three third-quarter field goals by Lambo&#8212;from 21, 31 and 32 yards out&#8212;added to the Chargers' lead. The middle score occurred after a fumble by Broncos' wide receiver Jordan Taylor. McManus missed wide-right on a 56-yard field goal at the end of the third quarter. Early in the fourth quarter, the Broncos' defense forced a Chargers' punt that backed up the Broncos to their own 3-yard line. On the next play from scrimmage, Broncos' offensive tackle Russell Okung was penalized for holding in the end zone that resulted in a safety, extending the Chargers' lead to 21-3. On the ensuing free kick, the Chargers committed another special teams turnover, with guard Kenny Wiggins fumbling the kick near midfield. The Broncos capitalized on this turnover, with a 5-yard touchdown pass from quarterback Trevor Siemian to wide receiver Bennie Fowler. The Broncos' defense forced a three-and-out on the Chargers' next possession with six minutes remaining in the game. On the sixth play of the Broncos' next drive, Siemian connected with running back C. J. Anderson on a 20-yard touchdown, however, another costly holding penalty on Okung negated the scoring play. Two plays later, Siemian connected on a pass completion to wide receiver Demaryius Thomas to the Chargers' 13-yard line, however, Chargers' linebacker Jatavis Brown forced a fumble off Thomas, which was recovered by cornerback Craig Mager, ending the drive with 3:35 remaining. The Broncos' defense forced another three-and-out, but used all three of their team timeouts in the process. A 46-yard field goal by McManus with 32 seconds remaining pulled the Broncos to within a 21-13 deficit. The Broncos recovered the onside kick at their own 46-yard line, however, four plays later, a desperation hail mary pass by Siemian fell short of the end zone. Special teams coordinator Joe DeCamillis served as interim head coach, while Gary Kubiak recovered from a migraine condition that he suffered during the previous week. As part of the NFL Color Rush program, the Broncos wore all-orange throwback uniforms. With the loss, the Broncos' NFL-record 15-game road winning streak against division opponents came to an end. This was the Broncos' final game in San Diego, as the Chargers relocated to Los Angeles after the 2016 season.
