The Minnesota Vikings won't announce a starting quarterback until Sunday morning, but signs still point to veteran Kelly Holcomb replacing the injured Tarvaris Jackson against Philadelphia. Jackson was listed as questionable on Friday's injury report with a broken index finger on his throwing hand. Coach Brad Childress said Jackson will either start or be the emergency third quarterback against the Eagles, in which case Holcomb would be the starter. "I'm still debating, the old game-time decision," Childress said. "You just want to see how a guy keeps coming, keeps coming." "I see him touch it a little bit better every day, and we'll just see if it will keep coming along."
