The San Diego offense had four drives of 65 or more yards on Monday night against the Indianapolis Colts but only one touchdown. Still behind a defense that yielded little the Chargers won 19-9.

The only touchdown of the game came in the second quarter when Chargers QB Philip Rivers hit Keenan Allen on a 22-yard scoring pass. That capped a 12-play 74-yard drive.

The Chargers (3-3) got Nick Novak field goals to finish three other long drives. That included a 31-yarder after a 17-play 79-yard drive in the second quarter; a 33-yarder after an 11-play 65-yard drive in the third quarter; and a 34-yarder after a 15-play 74-yard drive in the fourth quarter.

Novak's final field goal came with just two minutes remaining a 50-yarder that all but put the game on ice.

That was enough as the Chargers defense allowed just a trio of Adam Vinatieri field goals of 30 50 and 51 yards.

Colts quarterback Andrew Luck finished just 18 of 30 for 202 yards while Trent Richardson led Indianapolis (4-2) with 40 rushing yards.
