Steelers outside linebacker T.J. Watt has been added to the NFL Pro Bowl. Watt was added as an injury replacement Thursday for Houston Texans linebacker Jadeveon Clowney, who withdrew from the game because of injury. Watt led the Steelers with 13 sacks and has registered 20 career sacks, the most by a Steelers player in his first two seasons. Watt will be joined by Steelers defensive end Cameron Heyward, running back James Conner, wide receiver JuJu Smith-Schuster and center Maurkice Pouncey and guard David DeCastro.
