LaDainian Tomlinson and the Chargers are headed for a playoff clash with the Colts.

It was over when ...
Chargers DE Luis Castillo intercepted a Jay Cutler pass inside the Broncos' 20-yard line, setting up LaDainian Tomlinson's third touchdown of the game -- a 14-yard run -- on the following play. The score gave San Diego a 38-13 lead midway through the third quarter.

Game ball
It took 17 weeks, but Tomlinson finally looked like his old self, rushing for 96 yards and a season-high three touchdowns in less than three quarters. Tomlinson left in the fourth quarter with a possible abdominal strain and didn't return.
