The Texans signed Hairston to their practice squad Wednesday, Aaron Wilson of KPRC 2 Houston reports.
The 25-year-old fullback failed to make Houston's initial 53-man roster, but he's now been brought back as a practice squad player. Hairston missed all of 2023 due to a back injury, but he appeared in 16 regular-season games for the Texans in 2022, and he could potentially find himself back on the team's active roster at some point this season.
