A 6-yard touchdown pass from Philip Rivers to Antonio Gates extended San Diego’s lead to 10-0 midway through the second quarter.
The methodical, 15-play drive spanned the first and second quarters. The Chargers drove 86 yards in 8:47 of game time.
On the drive, the Chargers converted three third downs — two were third-and-1, and the third was for the touchdown.
After a penalty on the ensuing kickoff, the Broncos begin their next offensive series at their own 7-yard line.
