Washington had a chance to tie the game at the 4-yard line with less than 40 seconds to go in regulation, but the Vikings' defense forced three straight incompletions to hold on for victory.
Griffin was outstanding in the first half, throwing three touchdown passes on 16-for-21 passing for 179 yards. Alfred Morris had 88 yards rushing and the Redskins appeared to be on their way to an easy victory with a 24-14 halftime lead over a 1-7 Vikings squad.
The Vikings weren't ready to quit, however.
Christian Ponder shook off an interception on his second pass of the game to turn in a strong performance. He hit tight end John Carlson, who was starting in place of the injured Kyle Rudolph, for a 28-yard touchdown pass to bring the Vikings within six points. He then led the Vikings to the one-yard line on the next offensive possession.
Ponder took a hard hit on his left shoulder that forced him out of the game, but Matt Cassel took over and aptly handed the ball off to Adrian Peterson, who ran in for a one-yard touchdown to give the Vikings a 28-27 lead.
The Vikings held the lead for good from that point on. Cassel was much-maligned in Kansas City last season, but he played capably Thursday, leading the Vikings to two field goals in the fourth quarter.
Griffin, meanwhile, was unable to get back on track as the offensive line faltered. Sacks poured in during the fourth quarter, with several players joining the fun. Vikings defensive tackle Kevin Williams led the way with 2.5 sacks, Everson Griffen had one and Jared Allen added a half-sack.
Ultimately, the same problems that have bit the Redskins all season came back against Minnesota. The offensive line failed to keep Griffin upright in key situations and the secondary was picked apart by Ponder and Cassel, leaving another strong running performance wasted.
For the Vikings, the win is a shot in the arm in what had been a moribund season. For the 3-6 Redskins, the loss pushes them even more firmly to the edges of the NFC playoff picture.
