It didn't take long for Jason Allen to find a new home.
Allen, the 16th overall pick in 2006, started 19 games for the Dolphins and struggled to shake the label of draft bust. He won a starting job in training camp this season and is tied for ninth in the league with three interceptions, but he was badly beaten frequently and was replaced in the lineup last week by Sean Smith.
Allen was limited to special teams in Sunday's loss at Baltimore.
To make room for Allen, the Texans placed cornerback Domique Barber on injured reserve. Barber had arthroscopic knee surgery Thursday after he was injured during a special teams drill at Wednesday's practice.
"It's a tough guy to lose," Texans coach Gary Kubiaktold the team's official site. "He's been our most productive guy that's been on the field for us the most on special teams, and probably our most valuable player from that standpoint. So that's a big, big blow. We're going to have to have somebody step up this weekend, and we're going to have to decide who that's going to be."
