NEW YORK: Ben Roethlisberger passed for three touchdowns to lead the Pittsburgh Steelers to a 41-24 road victory over the St Louis Rams on Thursday.

The win kept the Steelers (10-5) on top of the AFC North Division, but it proved to be a costly one when running back Willie Parker broke his right leg on the second play of the game meaning he will miss the remainder of the season.

His replacement, Najeh Davenport, rushed for 123 yards and a touchdown and caught a TD pass.
