PITTSBURGH -- The Pittsburgh Steelers will be without their top receiving threat and best defender for the end of their preseason finale against the Detroit Lions . Wide receiver Diontae Johnson and linebacker T.J. Watt were both ruled out of Sunday's game. Watt left with a knee injury. Johnson appeared to awkwardly land on his shoulder as he was tackled while hauling in a 38-yard reception from Mitch Trubisky . Johnson exited during that drive and was evaluated in the blue medical tent before walking to the locker room. He was quickly ruled for the remainder of the game. The 26-year-old receiver signed a two-year extension earlier this month worth up to worth up to $39.5 million. The Steelers are already without receiver Chase Claypool and rookie fourth-round pick Calvin Austin III against the Lions after dealing with a shoulder injury and foot injury, respectively.
