Brett Favre has two extra days to recover from his concussion thanks to the winter storm that hit Philadelphia on Sunday but the two-day reprieve is unlikely to make it possible for the quarterback to play Tuesday night for the Minnesota Vikings against the Eagles.
Favre has not passed a concussion test and a team official told ESPN's Sal Paolantonio on Monday no test is planned before the game, meaning it is unlikely Favre will be cleared to play.
The extra 48 hours of rest is making it more likely Vikings running back Adrian Peterson, who has a bruised thigh, will play on Tuesday.
A week ago, the Vikings listed Favre as "out" for the game against Chicago with a sprained right shoulder. He was surprisingly upgraded to questionable the day of the game and ended up starting against the Bears.
Favre led the Vikings on a touchdown drive to open the game Monday night, but didn't make it through the second quarter after being sacked by Corey Wootton. Favre's head slammed off the frigid turf of TCF Bank Stadium and he was knocked woozy.
Favre, the NFL's iron man, had his consecutive starts streak snapped at 297 two weeks ago.
If Favre cannot play, rookie Joe Webb will make his first career start. Webb went 15 for 26 for 129 yards with two interceptions and a touchdown rushing in the 40-14 loss to the Bears. He took all the snaps with the first-team offense in practice this week.
