PITTSBURGH (AP) — Pittsburgh Steelers coach Mike Tomlin is optimistic star linebacker T.J. Watt’s balky ankle won’t keep him out of a showdown with rival Baltimore. The perennial All-Pro twisted his left ankle late in the fourth quarter of a 27-13 loss to Philadelphia. Watt said afterward X-rays on the ankle were negative. The 30-year-old was one of the few bright spots for the AFC North-leading Steelers (10-4) in the loss. Watt had two sacks and forcing a fumble. The Steelers would clinch the AFC North title with a victory over the Ravens.
