The Texans elevated former Philadelphia Eagles safety Grayland Arnold from their practice squad to their active roster along with defensive end Chris Smith.
Arnold was recently released from the Eagles' practice squad.
Wide receiver Phillip Dorsett was signed to the 53-man roster.
Arnold has played safety and nickel corner.
As a rookie, the former undrafted free agent from Baylor played in six games and recorded 10 tackles and one pass deflection.
A native of Beaumont, Arnold (5-foot-10, 187 pounds), was a two-time all-state basketball player and an all-state cornerback and an all-district quarterback and wide receiver at Kountze High School.
At Baylor, he had six interceptions in 2019 to rank second in the Big 12 Conference and returned one punt for a touchdown. He was named second-team All-Big 12. He declared early for the draft after that season, finishing his career with 107 tackles, seven interceptions and 7 1/2 tackles for losses.
Arnold's sister, Gabriell Mattox, played basketball at Texas.
This marks the second game in a row that Smith, a former Cleveland Browns and Jacksonville Jaguars pass rusher, was elevated.
The Texans re-signed wide receiver Damon Hazelton to the practice squad after releasing him earlier this week.
They placed running back Jaylon Samuels on the practice squad-reserve-COVID-19 list.
