Ben Roethlisberger left Thursday's practice early after rolling his ankle, says Mark Kaboly of the Pittsburgh Tribune-Review.

The Steelers are 2-3 heading into a crucial AFC North game against the Cincinnati Bengals on Sunday night, and knowing Roethlisberger, when he is banged up, he usually not only plays, but plays at his best.

So the Bengals should probably beware of Big Ben in this key divisional matchup with Thursday's happening regarding the quarterback's ankle injury.
