The Vikings aren't surprised that quarterback Brett Favre has undergone ankle surgery. Favre confirmed the procedure last Friday on his website. "I think that's some promising news," tight end Visanthe Shiancoe said. "Why'd he get ankle surgery? That's the first thing that came through my mind. Seems like he got it for the season, because that's what he needed to come back to the Vikings. But whatever's best for him and his family and for his old body -- old, old, old body, I stress that. He has to make a decision that's good for him." Favre has yet to make a decision on the 2010 season.
