The Jaguars (4-4) had only three other receivers on the roster — DJ Chark, Keelan Cole and Chris Conley — after putting Marqise Lee on injured reserve with a season-ending shoulder injury. Westbrook has 32 catches for 383 yards and a touchdown this season.
Walker has spent the entire season on Jacksonville's practice squad. If he plays against the Texans (5-3), he would make his NFL debut.
