This is no question the last thing the Pittsburgh Steelers wanted to see on Sunday going up against the Detroit Lions. In the middle of the action, star pass-rusher T.J. Watt sacked Jared Goff, but went down to the turf in pain.
Watt got his knee bent in a way it's not supposed to. You could tell just how much agony he was in.
That doesn't look good for the Steelers and Watt. If this indeed is a serious knee injury for the superstar player, it'll be a massive blow for Pittsburgh. Watt is no doubt one of the best defensive players in the league.
