Vikings' running back Adrian Peterson will be a game-time decision in today's game against the Panthers, according to the Pioneer Press. Peterson was limited in practice Friday because of a hamstring injury he suffered last Sunday. He is officially listed as questionable. "He'll treat here for the next 48 hours, and we'll look at (it) before the game," Coach Brad Childress said Friday. "I mean, you listen to the player, but sometimes you have to protect the player from himself and err on the side of caution," Childress added.
