The Houston Texans have signed rookie defensive end David Hunter to the active roster from the practice squad.

Hunter, an undrafted rookie from the University of Houston, was born in Houston and played at Waller High School.

He takes the roster spot of DE Tim Jamison who was lost for the season and placed on injured reserve after suffering a torn right Achilles tendon.

The fourth-year pro Jamison suffered the injury in the blow-out loss to the Green Bay Packers adding insult to injury. He had three tackles, one sack and one pass defensed in six games this season.

Hunter (6-2, 303) was named the Texans scout team defensive player of the week in three out of the six possible times this season. He is the second Houston practice squad player to find themselves promoted to the active squad this season joining guard Cody White, who was promoted last week.

Rookie defensive end Jared Crick, a fourth-round draft pick from Nebraska, could take Jamison's place as a rotational player behind J.J. Watt and Antonio Smith. Nose tackle Earl Mitchell also can play end.
