Collins (shoulder) was placed on injured reserve Tuesday.
The roster move ensures that Collins won't be available to play for the Texans until at least their Week 6 matchup with the Colts on Oct. 17. Though the details regarding Collins' shoulder injury remain vague, prior reports suggested that he faced a 3-4 week recovery timeline. Houston added tight end Antony Auclair from the practice squad to take Collins' spot on the 53-man roster.
