Pittsburgh Steelers quarterback Ben Roethlisberger has been ruled out of Sunday's game against the Baltimore Ravens.

A team source told ESPN that following Friday's practice, the Steelers were extremely pessimistic about Roethlisberger playing. The official injury report lists Roethlisberger as out.

Roethlisberger is not pain-free and continues to have problems with his injured right shoulder, affecting his ability to create enough torque to have velocity on his passes.
