However, Favre does not need surgery, and it still seems likely that he'll be on the field when the Vikings take on the Patriots in New England on Sunday.
According to Childress, Favre has both an avulsion fracture and a stress fracture, injuries revealed in an MRI. Favre, who had offseason ankle surgery, was limping noticeably during the game after getting hit on the ankle, and he was limping even more after the game. (Of course, when he briefly believed he had hit Percy Harvin for a game-winning touchdown late in the fourth quarter Sunday night, Favre was running around like he could do a 4.4-second 40-yard dash.)
Favre will be in a walking boot throughout the week, which could keep him from practicing. Childress says players typically need to practice in order to play.
But Favre isn't a typical player, and the Vikings aren't paying Favre $1 million a game to stand on the sideline. If he can walk, expect Favre to play.
Childress, however, would not commit to a starting quarterback for Sunday, other than to say, "We have to do what's right for the Minnesota Vikings."
