Brett Favre

The Eagles' matchup against the Vikings in Philadelphia has been postponed until to 8 p.m. ET on Tuesday due to a blizzard, the Eagles announced Sunday.

The blizzard is expected to dump up to 20 inches of snow in Philadelphia, where the Vikings were scheduled to play the Eagles on Sunday night.

According to Comcast SportsNet Philadelphia, a winter storm warning is in effect until 1 p.m. ET Monday. A state of emergency will go into effect Sunday in Philadelphia at 2 p.m. ET, about six hours before the original scheduled kickoff.

This isn't the first time the Vikings have been impacted by weather this season. The team's Week 14 game against the New York Giants had to be moved to Detroit after heavy snow forced the Metrodome roof to leak, then collapse. The Vikings then had to play their next game, a Monday night meeting with the Chicago Bears, at the University of Minnesota's TCF Bank Stadium.

For those relying on Joe Webb, he becomes a considerably more risky start on Tuesday, with Brett Favre given 2 more days to get healthy. Adrian Peterson becomes less risky, but could still be a game-time decision. Percy Harvin & Sidney Rice would be better options if Favre starts, but even with Favre that's not a sure thing.

All Eagles become safer plays with the game postponed until the weather clears - DeSean Jackson, Jeremy Maclin, LeSean McCoy & Michael Vick.

Fantasy owners playing in the championship game this week will have their nerves shot, with many games hinging on outcomes we wont know until Tuesday night.
