Vikings vs. Ravens 2013: Joe Flacco throws game-winning TD with 4 seconds left

But, it wasn’t just that they were throwing snowballs: it was where they were throwing them:

Of course, the only part of this the NFL will care about is Peterson criticizing officials, which could cost him.

The Ravens drove down to the red zone with two minutes left and took the lead thanks to Dennis Pitta. Making his season debut after dislocating his hip in training camp, Pitta caught the go-ahead touchdown pass with two minutes left to give the Ravens the lead back. They got the two-point conversion to extend the lead to 15-12.

Things were quiet for much of the first half, but the Vikings suffered a big loss in the second quarter. Adrian Peterson went down with an ankle injury and was carted to the locker room, replaced by Gerhart. Blair Walsh managed to get a 39-yard field goal off in the snowy weather and the Ravens went into halftime leading, 7-3.

Update: NFL Network’s Ian Rapoport reports that Peterson has a mid-foot sprain. He’s back on the sideline but will not come back in.

Before the injury, Peterson had 13 yards on seven carries, struggling to get things going in heavy snow conditions. He leads the NFL with 1,208 rushing yards and is the most important player on Minnesota’s offense. His loss would be devastating to the Vikings, who are already out of the playoff race and don’t have many other credible weapons on offense.

Game Date/Time and Location: Sunday, Dec. 8, 1 p.m. ET at M&T Bank Stadium, Baltimore, Md.

Thanks to three wins in their last four games, and a struggling AFC that’s opened the door for a .500 team to possibly win a wild card berth, Baltimore might just get their shot.

But as we’ve seen all season long, that hardly means that this is going to be an easy win for Baltimore.

Head coach John Harbaugh said that Pitta has a “reasonable chance” of playing Sunday, barring any setbacks.

Baltimore is holding onto the sixth and final AFC playoff spot currently at 6-6, and could move into great position with a win over the 3-8-1 Vikings. The Ravens have won two straight games and look primed to make a nice run into the postseason. That is, if they don’t stumble on their way there.

It is also a clean sweep with our guys here at SB Nation, with all six taking the Ravens to get over the .500 mark.

Baltimore is 6-2 against the spread in its last eight games.

Cassel came into that game in relief of Ponder and was 22 of 33 for 243 yards, one touchdown and one interception, as the Vikings pulled off a 23-20 upset in overtime.

He will likely be the backup on Sunday against Baltimore.
