The Texans worked out defensive tackle Auzoyah Alufohai, according to a league source not authorized to speak publicly.
Alufohai wasn't immediately signed to a contract.
Alufohai was released during the preseason after trying to crack one of the most crowded positions on the roster.
Alufohai has spent time on the Chicago Bears' practice squad this season since being released by the Texans.
Alufohai (6-foot-4, 320 pounds) was signed as an undrafted free agent from Division II program West Georgia. Alufohai played against the Indianapolis Colts last season after being promoted to the active roster from the practice squad, assisting one one tackle. He played in three games overall last season.
