The Vikings are getting Tarvaris Jackson ready to play. No, there's no immediate concern about Brett Favre going down, but he has suffered a number of ailments through the first half of the season — a worrisome ankle, bad ribs, an unknown illness that required antibiotics, and now a strained groin that was trouble before the Packers game. Jackson has impressed in limited snaps lately, and the team would like him to get work if the Vikings are in a blowout situation. Source: Pro Football Weekly
