The Cardinals didn't make any more moves before Tuesday's trade deadline, but they did add a linebacker on Wednesday.
The team signed Kamu Grugier-Hill, who had been cut by the Texans last week when Grugier-Hill asked for his release because of dwindling playing time.
To make room on the roster, the Cardinals waived kicker Rodrigo Blankenship with an injury settlement.
The Cardinals also made multiple practice squad moves, releasing offensive linemen Danny Isidora and Sage Doxtater and signing back offensive lineman Rashaad Coward along with defensive lineman Eric Banks.
Grugier-Hill is coming off his best season in 2021, with three sacks, an interception and a team-best 108 tackles for the Texans. He had 13 tackles for loss. This season, in six games, he had 40 tackles, one for loss.
Drafted by the Patriots in the sixth round in 2016, he has also spent time with the Eagles and Dolphins.
"We really just found a player that we felt was really playing at a high level and could add some value as we move on throughout the season," coach Kliff Kingsbury said. "That's all it came down to. (He was) a really productive player there in Houston."
Kingsbury said Grugier-Hill will play as an inside linebacker, and help on special teams.
