The Texans will place Kayvon Webster on injured reserve, according to Ian Rapoport of NFL.com (on Twitter). It’s currently unclear whether Webster will be a candidate to return later this year.

Webster spent the first four years of his career as a reserve with the Broncos, but signed a two-year deal with the Rams last spring. The reunion with defensive coordinator Wade Phillips did not go as planned, and neither has his reboot with the Texans. Webster joined the club in late August, but an Achilles injury prevented him from playing in the first four games of the season. He returned this past week to face the Cowboys, but he suffered a quadriceps injury that will shut him down for a while.
On Tuesday, the Texans elevated defensive back Mike Tyson from the practice squad to help fill in for Webster. The Texans could elevate Shareece Wright to the starting lineup to replace Webster, or they could shift Kareem Jackson over from safety and use Justin Reid as a first-stringer in the middle.
