The Texans signed Vaughn to the practice squad Tuesday, Aaron Wilson of KPRC 2 Houston reports.
Vaughn had a brief stint with the Texans in August before being waived ahead of Week 1. The 24-year-old has not played in a regular-season game since the 2024 season, where he recorded 17 rush attempts for 70 yards and caught three of five targets for 18 yards.
