The move corresponds with defensive tackle Hassan Ridgeway returning from IR. Littleton was signed to the Texans' 53-man roster Tuesday after being let go by the team less than a week earlier. He'll have a chance to explore his options should he clear waivers.
Houston let go of Littleton last week in order to add Myjai Sanders to its active roster, but it now seems as if the team has found an open spot for the 29-year-old linebacker. Littleton has appeared in 116 games throughout his eight-year NFL career, recording 543 total tackles, 27 tackles for loss and 9.5 sacks, along with earning second-team All-Pro honors in 2018.
