Vikings Pro Bowl cornerback Antoine Winfield is not practicing for a third consecutive day because of a sprained right foot and isn't expected to play Sunday against Pittsburgh at Heinz Field.

The Vikings will issue their injury report later today and my guess is that Winfield will be listed as doubtful but considering he was still wearing a walking boot on Thursday the odds of him playing would appear to be almost nill.

During the brief portion of practice the media was allowed to watch, the Vikings worked on their nickel defense with Karl Paymah at left corner and Benny Sapp playing in the slot, as he usually does. It will be interesting to see what the Vikings do on Sunday. It wouldn't be surprising to see the Vikings use Sapp at the left corner and then have him move inside and Paymah play the outside in passing situations.
