One man's prediction: The Vikings showed good offensive balance in the second half last week behind Adrian Peterson's relentless running and Matt Cassel's efficient passing. Cassel gets another crack as the starter because of Christian Ponder's concussion. The Vikings still are engaged mentally and playing hard despite their record, but the Ravens are a tough team at home.
What injury?
A nagging groin injury essentially has eliminated Adrian Peterson's ability to practice during the week and allegedly taken away some of his explosiveness. His production doesn't reflect that, though. In his two past games, Peterson has rushed for 357 yards on 67 carries. The Ravens own the sixth-ranked run defense in the NFL, so this should be a tougher test than the dreadful run defenses of the Packers and Bears.
