Pittsburgh Steelers quarterback Ben Roethlisberger left Thursday's practice after turning his right ankle but expects to play on Sunday against Cincinnati.

Roethlisberger says he stepped on a teammate's foot while dropping back to pass but insisted he is fine. He spent the latter portions of practice in the training room but was with the rest of the team when the locker room was open to the media afterward.

Dealing with ankle injuries is nothing new to Roethlisberger, who played the final month of the 2011 season with a badly sprained left ankle. He is off to the best start of his career and currently ranks fourth in the NFL with a 99.9 quarterback rating for the Steelers (2-3).
