Nickel cornerback Bryant McFadden is doubtful for Sunday’s game with the Seahawks with a high ankle sprain.  He could miss up to 1 month with this injury.  McFadden has made 12 tackles this season and he also has recovered a fumble and intercepted a pass this season that he returned 50 yards for a TD.  The Steelers will miss McFadden’s playmaking ability in the nickel and dime packages.
