The Texans made several moves ahead of their Week 1 game against the Colts.
They placed defensive end Mario Addison (thigh) on injured reserve. Addison will have to miss at least four games before returning to the active roster.
Addison signed with Houston in May, reuniting with Texans defensive line coach Jacques Cesaire after the two were together with the Bills. He appeared in all 17 games with the Bills last season and totaled 29 tackles, seven sacks and two forced fumbles.
