Steelers fear T.J. Watt suffered torn pectoral muscle

The Pittsburgh Steelers defensive unit took a potentially devastating hit during its Week 1 overtime win against the Cincinnati Bengals. 

Star pass rusher and 2021 Defensive Player of the Year T.J. Watt left the game in the fourth quarter after suffering a pectoral injury. The Steelers believe he likely tore the muscle, ESPN reported.

The Steelers will know more on Monday after he undergoes an MRI, but losing Watt for an extended time would be a significant blow to Pittsburgh.

Before the injury, he was his usual disruptive self, with a sack and an interception.

Last year, he tied the NFL single-season sacks record with 22.5 last season despite missing two games.
