Case Keenum and T.J. Yates each threw a touchdown pass in their battle for the backup job, and Cierre Wood and Dennis Johnson combined for 187 yards rushing, leading lead the Houston Texans past the Dallas Cowboys 24-6 in a preseason finale Thursday night. Keenum directed touchdown drives of 87 and 80 yards, the latter capped by a 27-yard touchdown pass to Lestar Jean. Yates, the backup to Matt Schaub the past two seasons, threw a 21-yard scoring pass to Andy Cruse and led another drive to a field goal. Alex Tanney was under pressure and struggled in his bid get Dallas to keep a third quarterback behind Tony Romo and Kyle Orton. He was 17 of 31 for 177 yards with an interception.
