Ben Roethlisberger took a break from changing his newborn son’s diapers to throw a few passes with his sprained right shoulder on Monday.

The Pittsburgh Steelers (6-5) saw enough to ask their franchise quarterback to throw a few more over the next few days, hoping he can recover in time to salvage a season in danger of slipping through their fingers.

Calling the session “a step in the right direction,” coach Mike Tomlin said Tuesday there’s “a chance” Roethlisberger could play on Sunday in Baltimore (9-2).

Safety Troy Polamalu and wide receiver Antonio Brown could both play Sunday. Polamalu has been limited to just five quarters all season due to a right calf injury, though Tomlin said he’s “encouraged” by Polamalu’s progress.
