The Texans have signed fullback Moran Norris and defensive end Keith Browner, who tried out for the team at mini-camp this week.
Wide receiver Mike Sims-Walker and linebacker Prescott Burgess also tried out at the Texans' three-day mini-camp. They have not been signed.
Norris (6-1, 250) played for the Texans from 2002-05. The 33-year-old Houston native spent five of the last six seasons with the San Francisco 49ers and 2008 with the Detroit Lions. He provides a physical presence to complement versatile starter James Casey, converted practice squad linebacker Derrell Smith and undrafted rookie Jason Ford.
Browner (6-4, 276) went undrafted out of California in 2011. This is his first NFL team. As a senior at Cal, he played outside linebacker and started nine games with 28 tackles. Browner's father, Keith Browner, and uncles Ross, Joey, Willard and Jim Browner all played professional football.
The Texans now have 89 players on their active roster. That number includes wide receiver Dwight Jones, who left the team early in organized team activities (OTAs) and did not return. The NFL roster limit is 90 players.
