Adam Vinatieri kicked a 30-yard field goal on the game's first possession, and the Indianapolis Colts led the San Diego Chargers 3-0 after one quarter Monday night.
The Colts opened the game with a flea-flicker, with Trent Richardson taking the handoff and tossing the ball back to Andrew Luck, who completed a 35-yard pass to Reggie Wayne. The drive bogged down at the Chargers 11, leading to Vinatieri's field goal.
Philip Rivers' first four passes for San Diego were incomplete. Then he connected with rookie Keenan Allen on a 13-yarder on third-and-15 from the Chargers 33.
The Colts were trying to take a two-game lead in the AFC South.
Colts coach Chuck Pagano is the older brother of Chargers defensive coordinator John Pagano.
The Chargers were without three starters: linebackers Jarret Johnson and Donald Butler, and left guard Chad Rinehart. The Colts were without safety LaRon Landry.
