Pittsburgh Steelers star T.J. Watt exited Sunday's game against the Cincinnati Bengals.
As he walked off the field in the fourth quarter, the CBS cameras captured him immediately appearing to say he injured his pectoral muscle. The team confirmed that was the source of the issue.
Watt suffered a knee injury in his team's last preseason game, but head coach Mike Tomlin said afterwards there was "no long term concern."
The Steelers need the pass-rusher healthy if they are going to stay in contention in the deep AFC North.
