American Football: Manning sets record for touchdown passes in comeback win

Peyton Manning threw two touchdown passes to break the National Football League's single-season record and rally the Indianapolis Colts from a 15-point deficit in the final quarter to a 34-31 overtime victory over the San Diego Chargers.

The victory on Sunday was the eighth straight for the Colts (12-3) and ensured Indianapolis will be at least the No. 3 seed in the AFC playoffs.

San Diego's winning streak ended at eight games. The Chargers (11-4) will still host a first-round game as the No. 4 seed.

Manning, who tied Dan Marino's record on a 3-yard shovel pass to James Mungro, threw a 21-yard TD pass to a wide open Brandon Stokley with 56 seconds left in regulation to break the record. Edgerrin James then ran for the 2-point conversion to tie the game at 31, a play Manning called at the line.

In overtime, Manning hooked up with Stokley on a 23-yard gain, then found Reggie Wayne on a 35-yard catch-and-run, setting up Mike Vanderjagt's winning field goal from 30 yards with 12:13 to go.

In Pittsburgh, the Steelers wrapped up home-field advantage in the AFC as Ben Roethlisberger threw two touchdown passes before leaving the game with a rib injury.

The Steelers (14-1) won't have a meaningful game until Jan. 15 or 16. But a team that has been playing without six injured regulars sustained two more injuries, as both Roethlisberger and cornerback Deshea Townsend (wrist) left the game in the fourth quarter.
