PITTSBURGH -- Bernard Berrian refused to discuss the injury he suffered during the Vikings' 27-17 loss to the Steelers today at Heinz Field, but the wide receiver was wearing a wrap on his left leg as he dressed in the locker room.

The injury appears to be Berrian's hamstring given that the wrap was on his thigh. Berrian suffered a hamstring injury in the Vikings' preseason opener at Indianapolis but in that case it was his right hamstring. Berrian had two receptions for 18 yards before leaving the game.

Meanwhile, cornerback Antoine Winfield said he has a sprained right foot and considers himself day-to-day, refuting an ESPN report that he will be out four-to-six weeks. Winfield had a walking boot on his foot as he left the Vikings locker room.

As for Brett Favre, the veteran quarterback was sacked four times today and took a big hit from linebacker James Harrison to end the game. "It would have felt a lot better had we won, obviously," Favre said when asked about his physical well being following the game. "But right after the game it's hard to tell, either way. The last one was a pretty good shot. It's disappointing, phyiscally, we knew it would be a Pittsburgh matchup, that's what they do."
