The Indianapolis Colts (9-7) are preparing for their biggest game of the season. 

The winner of their Week 18 matchup with the Houston Texans (9-7) is heading to the playoffs, while the loser's season will come to an end. 

The Colts got the majority of their players back on the field for practice yesterday but were without starting center Ryan Kelly. To make it worse, Kelly watched practice with a boot on his foot, which has many concerned about his availability this week. If the past means anything, though, Kelly is a tough son of a gun, and I simply can't see him missing a winner gets in game like this one if he has any say in the matter.

Thursday injury report: 

Will update with the official injury report following the team's Thursday practice.
