Roethlisberger, who's suffering from a sprained right shoulder and dislocated rib, fully practiced Wednesday.
"I'm getting there," Roethlisberger said, via The Associated Press. "I've got to talk to (tight end) Heath (Miller). He's my barometer. He lets me know how close I am to 100 percent on velocity and stuff like that."
"We'll see what (Thursday) holds for us," Tomlin said, via The AP. "We'll make sure that there (are) no steps backward (Thursday) morning."
