PITTSBURGH (AP) — The Pittsburgh Steelers could have outside linebacker T.J. Watt back for their “win or go home” showdown with Baltimore for the AFC North title on Sunday night. Coach Mike Tomlin said Tuesday he's “more optimistic” than he has been that the perennial Pro Bowl edge rusher will be available after sitting out each of the past three games while recovering from surgery to repair a partially collapsed lung sustained following a dry needling treatment. Tomlin added he'd like to see Watt practice fully at some point this week.
