Woodley hasn't played since injuring his ankle during the Steelers' 20-14 loss on the road to the Cleveland Browns on Nov. 25. The pass-rushing linebacker is a disruptive presence in Pittsburgh's defense, with four sacks, one forced fumble and one interception in 10 games this season for the Steelers.
Without him for the last two weeks, Pittsburgh defeated the Baltimore Ravens on the road, 23-20, in Week 13 but, in the return of quarterback Ben Roethlisberger, fell to the San Diego Chargers at home last Sunday, 34-24.
The Steelers rank in the top five in both passing yards allowed (an average of 169.2, first in the NFL) and rushing yards allowed (93.2 given up on average, good for fifth in the NFL). The addition of Woodley, and the fact that the Cowboys simply must account for him on the field, figures to make their defense all the tougher.
