Steelers coach Mike Tomlin doesn't expect Ben Roethlisberger's fractured right thumb to be an issue on Sunday. Tomlin says that Roethlisberger will start at quarterback against the Chiefs and while the coach can't tell how much the thumb will affect him, he expects Roethlisberger to be effective. "Those of us who know Ben understand that he's going to show and show for his teammates," Tomlin said.
