The Indianapolis Colts will take on the St. Louis Rams in the third preseason game tonight, and it's the game in which the starter typically play the most of any preseason game. This is the biggest tune-up for the regular season, and so this is the game that we'll see the starters in the most and will start to get an idea of how good they will be.

Of course, teams are still being cautious with injured players, as the result still doesn't matter in this game. The Colts are one of those teams taking it easy with guys who have been hurt, and their inactive list for tonight's game lists several key players. Here's the list of those players who won't be playing tonight, followed by a few notes:

Phillip Dorsett, WR (knee)

Vick Ballard, RB

Greg Toler, CB (neck)

Deveron Carr, CB

Nate Irving, ILB (knee)

Donald Thomas, OL (quad)

Hugh Thornton, OL (knee)

Coby Fleener, TE (ankle)

Robert Mathis, OLB (Achilles)
