The Pittsburgh Steelers are riding high following their Week 16 upset victory over the Detroit Lions and are the clear-cut frontrunners in the AFC North with a 9-6 record. Unfortunately for the Steelers, they will be without their best player as they try to clinch the division on Sunday against the Cleveland Browns.

Cleveland Browns edge rusher Myles Garrett could end up breaking Pittsburgh Steelers star T.J. Watt’s sack record right in front of the man who tied Michael Strahan with 22.5 sacks all time.

Pittsburgh Steelers star T.J. Watt could return from a partially collapsed lung in Week 18 or at the beginning of the playoffs, according to NFL Network's Tom Pelissero.

Safety Jalen Ramsey (illness) and left guard Isaac Seumalo (triceps) are listed as questionable. Wide receiver Calvin Austin (hamstring), cornerback Brandin Echols (groin), and cornerback James Pierre (calf) will join Watt on the inactive list.

According to ESPN’s Adam Schefter, the pass rusher’s return to play “remains murky and uncertain.” At the moment, Watt’s focus is solely on his recovery, with his potential return to field being considered “secondary.”

Pittsburgh linebacker T.J. Watt participated in practice all week, leaving the decision of whether to play him Sunday at Cleveland in the hands of Steelers head coach Mike Tomlin.
