Steelers' quarterback Ben Roethlisberger left Sunday's game against the Browns on a cart after suffering a concussion. However, Pittsburgh coach Mike Tomlin claimed after the game that all tests looked good. "To this point, all the tests are negative, which, of course, is positive," Tomlin said during his postgame press conference. "We're optimistic about where he's going to be capable of being. Again, the bye is going to be helpful in regards to that. ... [Tests] are negative, which is encouraging."
