The Texans re-signed Littleton to the team's 53-man roster Tuesday, Aaron Wilson of KPRC 2 Houston reports.
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.
