Pittsburgh Steelers head coach Mike Tomlin declined an opportunity to name a starting left cornerback, an indicator that 2009 third-round pick Keenan Lewis has an opportunity to overtake Bryant McFadden for the spot opposite Ike Taylor.

"I think that Keenan Lewis has really had a good camp and showing that he's maybe prepared to take the next step," Tomlin said. "We're going to continue to give him looks and exposure. If he makes enough plays and gets our attention, we'll consider playing him if he's worthy."

Lewis (6-0, 208) appeared in just four games as a rookie, making one special teams tackle against the Kansas City Chiefs before being placed on injured reserve in the final week of the season with a back injury.

McFadden, re-acquired during the 2010 NFL Draft after a season with the Arizona Cardinals, started the pre-season opener against the Detroit Lions and is expected to start on Saturday night against the New York Giants.
