PITTSBURGH -- The Pittsburgh Steelers' defense took two hits before Sunday's game against the Las Vegas Raiders even started, and by halftime, they were down four starters, including T.J. Watt.
Watt went down with a groin injury in the second quarter and was officially ruled out after halftime. Both cornerback Joe Haden and linebacker Devin Bush also had groin injuries -- theirs sustained during Friday's practice -- that kept them out of the 26-17 loss.
In addition, Steelers wide receiver Diontae Johnson suffered a knee injury on the final play of the game, an 11-yard reception from Ben Roethlisberger, and nose tackle Tyson Alualu fractured an ankle in the first quarter, coach Mike Tomlin said, leaving him sidelined for an "extended" time.
