The Houston Texans made a few roster moves Monday before former Texan Mario Williams and the Buffalo Bills come to town.

Houston signed nose tackle Terrell McClain to the active roster to replace rookie defensive end David Hunter, who landed on injured reserve with a toe injury.

The Texans also re-signed offensive tackle Nick Mondek and defensive end Keith Browner to their practice squad, while releasing defensive tackle Lamar Divens and linebacker Cameron Collins off the practice squad to create room.

McClain was a third-round draft pick by the Carolina Panthers out of South Florida in 2011. He started the first 12 games of his rookie season recording 19 tackles and a sack before suffering a season-ending left knee injury.

Hunter was signed two weeks ago from the practice squad. He suffered a season-ending injury during his second practice as a member of the active roster.

The Texans selected Mondek in the sixth round of this year’s draft out of Purdue. He was released in the first round of preseason roster cuts on Aug. 27 and spent some time on the Oakland Raiders’ practice squad. Browner, after going undrafted in 2011, signed with the Texans in June after a trying out in mini-camp. He was released in the final round of cuts on Aug. 31.
