The Texans signed former Boston College linebacker Connor Strachan to the practice squad.
The Texans officially terminated defensive end Whitney Mercilus and kick returner Andre Roberts' contracts.
Strachan last played in The Spring League. He has also played in the XFL.
Strachan had 267 career tackles, nine sacks and three interceptions in college as a third-team All-ACC selection before signing with the Jacksonville Jaguars as an undrafted free agent.
