The Pittsburgh Steelers are set to take on the Dallas Cowboys in a pivotal playoff positioning game for both teams, but Pittsburgh will be without key members of their secondary against the likes of Dez Bryant and Miles Austin.
Ike Taylor missed the team's 34-24 loss at home to the San Diego Chargers last week with a leg stress fracture, which broke his consecutive games played streak at 135. He has also been ruled out for Sunday's game against Dallas.
Elsewhere in the secondary, cornerback Cortez Allen was listed as questionable on Tuesday, as he continues to recover from a hip flexor injury. Keenan Lewis is also recovering from a hip flexor ailment.
The list of injured players means second-year veteran cornerback Curtis Brown will see more playing time, along with practice squad player Josh Victorian.
Dallas averages 292.2 passing yards per contest, which ranks third-best in the league. Quarterback Tony Romo has 20 touchdown passes and 3,928 yards through the air, which is fourth-best in the NFL.
