Roethlisberger told reporters his ankle was "a little better each day" and he wanted to see how it responded to practice.
"It would be nice to get an extra week of rest, but I prefer to play," Roethlisberger said about resting the ankle in Sunday's regular-season finale against the Cleveland Browns.
Coach Mike Tomlin said Monday that Roethlisberger had "a shot" to play after sitting out the Steelers' 27-0 victory over the St. Louis Rams. Roethlisberger first sustained the injury Dec. 8 against the Cleveland Browns and played through the injury the following week in the Steelers' loss to the San Francisco 49ers, but he was noticeably hindered by the injury.
Linebacker James Harrison (neck), guard Doug Legursky (shoulder), safety Troy Polamalu (knee) and running back Mewelde Moore (knee) all missed practice for the Steelers on Wednesday. Wide receiver Mike Wallace (ankle) and linebacker LaMarr Woodley (hamstring) were limited.
