What it means: The Vikings are now 2-0 since interim coach Leslie Frazier took over for Brad Childress. They remain on the far fringes of the playoff hunt at 5-7, trailing nine other teams for six NFC playoff spots. But they're due for an interesting week while trying to determine whether quarterback Brett Favre can recover from a sprained shoulder in time to start next Sunday against the New York Giants.
FavreWatch: Favre sprained his right shoulder on the third play of the game after a hit by the Bills' Arthur Moats. He spent most of the game watching from the sideline in full uniform, but Frazier said the team's medical staff had already ruled him out for the remainder of the game. Favre has proved he has a high pain tolerance, most recently by playing with two fractured bones in his left foot. But a quarterback's throwing shoulder is an entirely different story. Frazier said Favre will remain the starter "if he's healthy." But it's hard to play quarterback with a sprained shoulder.
T-JackWatch: I'm not sure if backup Tarvaris Jackson had a chance to wrest the starting job away from Favre with a sterling performance, but his performance Sunday made that a moot point. As per his custom, he mixed in some beautiful throws and nice runs with a few head-scratchers, most notably a first-quarter interception that Bills cornerback Drayton Florence returned for a touchdown. His 31-yard touchdown pass to receiver Sidney Rice was thrown into double coverage and required a highlight-reel catch to avoid an interception. Overall, Jackson completed 15 of 22 passes for 187 yards, two touchdowns and three interceptions.
PetersonWatch: Tailback Adrian Peterson, running behind a line that was without left guard Steve Hutchinson (thumb), sure didn't look like he spent most of last week sidelined by a sprained ankle. He tallied three touchdowns and looked as fast as ever on a 43-yard touchdown gallop in the fourth quarter.
What's next: The Vikings will host the New York Giants next Sunday at the Metrodome.
