The Indianapolis Colts are preparing for a pivotal Week 18 showdown against the Houston Texans with significant personnel challenges, as four key players have been officially ruled out of Sunday's crucial game.

Head Coach Shane Steichen confirmed that cornerback Sauce Gardner, who recently returned from a three-week calf injury hiatus, will not participate after re-aggravating his condition during last week's contest. Gardner's absence represents a notable blow to the Colts' defensive secondary, especially in a game with potential playoff implications.

Tight end Will Mallory's unexpected lung injury has further complicated the team's roster strategy. Steichen described Mallory's condition as 'hard to explain', leaving the Colts with limited options at the tight end position. With Drew Ogletree on injured reserve, only Tyler Warren and Mo Alie-Cox remain healthy at the position.

Quarterback Anthony Richardson and safety Daniel Scott have also been ruled out, both remaining on injured reserve. Richardson's absence was confirmed early in the week, continuing his recovery from an eye injury that has sidelined him for an extended period.

On a more positive note, several players are set to return to the lineup. Tanor Bortolini (concussion), Dalton Tucker (shoulder), and JT Tuimoloau (oblique) will all be available for Sunday's game after missing the previous week's matchup against Indianapolis.

The Colts' depth will be tested as they navigate these injury challenges, seeking to maintain competitive performance in their season finale against the Texans. With multiple key contributors sidelined, younger players and backup athletes will have critical opportunities to demonstrate their capabilities in this high-stakes encounter.

As the team prepares for this final game, Coach Steichen and his staff will need to implement creative roster management and strategic adjustments to compensate for the missing personnel and maximize their competitive potential.
