Will Mallory: Everything you need to know

Mallory (lung) has been ruled out ahead of Sunday's matchup against the Texans, Amanda Foster of the Colts' official site reports. Mallory was unable to practice Wednesday or Thursday and is now in line to miss the Week 18 divisional matchup due to a lung issue. The third-year pro from Miami appeared in just two games for Indianapolis this season, catching his lone target for 16 yards across 16 offensive snaps. While Mallory is sidelined Sunday, expect Tyler Warren and Mo Alie-Cox to serve as the Colts' top tight ends.

Mallory (lung) was estimated as a non-participant in Wednesday's practice walkthrough. It's not clear when Mallory was hurt, though it may have been Sunday against Jacksonville, when he logged a season-high 11 offensive snaps and made his first catch of the campaign. With the Colts officially eliminated from playoff contention, Mallory could see more work Sunday versus Houston if he's able to suit up, but the lung issue could throw a wrench in that potential opportunity. Mallory will have two more days this week to get onto the practice field before Indianapolis assigns injury designations.

Mallory (coach's decision) is inactive for Sunday's game against the Falcons in Berlin. Mallory has been a regular on the Colts' inactive list, having suited up for just one game all season (Week 5 against the Raiders) and playing five total snaps in that contest. He'll continue to be in street clothes on game days so long as the Colts' top three tight ends -- Tyler Warren, Mo Alie-Cox and Drew Ogletree -- are all available.
