PITTSBURGH -- Steelers inside linebacker Devin Bush's day is done with a knee injury sustained late in the second quarter against the Cleveland Browns.
Bush, who came racing across the field late in the second quarter, dove to make a tackle on running back D'Ernest Johnson. Bush missed Johnson and moved awkwardly on his left knee, grabbing it as he fell and rolled out of bounds.
He needed help getting off the sideline, walking off gingerly with his arms around head athletic trainer John Norwig and another team official.
