MINNEAPOLIS -- Adrian Peterson has his sights set squarely on 2,000 yards. Thanks to his latest jaw-dropping performance and an opportunistic defense, the Minnesota Vikings still have their eyes on the playoffs.
Peterson rushed for 154 yards and two touchdowns and Harrison Smith returned an interception for a score to lead the Minnesota Vikings to a 21-14 victory over the free-falling Bears on Sunday.
Jay Cutler was 22 for 44 for 260 yards, one touchdown and two interceptions and couldn't finish the game for the Bears (8-5), who have lost four of their last five. He took a wicked hit to the head from Everson Griffen in the fourth quarter, remained in the game for the rest of that drive, but was replaced by Jason Campbell with 3 minutes to play.
There was no immediate word on Cutler's health, and Campbell threw a 16-yard TD to Brandon Marshall with 1:48 to play, but Kyle Rudolph recovered the onside kick to seal the victory.
Peterson topped 100 yards before the first quarter was over, helping the Vikings (7-6) overcome another lackluster day from quarterback Christian Ponder to get a victory that will keep their playoff hopes alive.
Marshall had 10 catches for 160 yards, but Chicago's struggling offense couldn't do enough to overcome the two turnovers and Peterson's relentless effort.
Peterson's remarkable comeback from a torn ACL late last season seems to get more impressive every week. Not even a year removed from that major injury in Washington, he broke the 100-yard mark for the seventh straight game. He has 1,600 yards with three games to play, putting a hallowed 2,000-yard season within reach. He ran for 51 yards on the opening play of the game and continued to gash the broken-down Bears the rest of the way.
No one was happier to see it than Ponder, who continued to look skittish in the pocket and out of whack with his mechanics. He finished 11 of 17 for 91 yards, including an ugly interception off his back foot late in the first half.
For once, his performance didn't doom the Vikings.
Vikings fans trudged through a snow storm to get to the Metrodome, and they were ornery and ready to give Ponder all the grief they could. They booed him in pregame introductions, then Peterson touched the ball on five of six plays in the opening drive. He also ripped off a 16-yard run and finished it with a 1-yard TD.
Josh Robinson intercepted Cutler on the next possession, returning the ball to the Chicago 5 to set up Peterson's second touchdown. The Vikings were off and running, exactly what they were hoping to do.
Cutler responded, hitting Alshon Jeffery with a 23-yard TD pass that got a healthy contingent of Chicago fans chanting "Let's Go Bears!"'
Just as the Bears appeared to seize momentum, Cutler floated a pass over Marshall's head right into the arms of Smith, who headed down the Chicago sideline for a 56-yard touchdown late in the third quarter and a 21-7 lead.
The Vikings haven't made big plays in the passing game ever since Percy Harvin was lost for the season with a severely sprained left ankle against Seattle on Nov. 4. They finally did it Sunday, but it was the defense that made it happen.
Robinson and Smith combined for 100 return yards, more than the Vikings' passing game had through the air.
Now the Bears must try to hold off another December malaise under coach Lovie Smith. They started 7-1, but Smith tried to ratchet up the intensity this week, saying the Bears had to win out to get into the playoffs.
Cornerback Tim Jennings was out with an injured shoulder and linebacker Brian Urlacher, the man in the middle of the proud veteran defense, could be out for the rest of the season with an injured hamstring. Defensive tackle Henry Melton hurt his shoulder in the first half and kicker Robbie Gould was limited by a strained left calf that he suffered in pregame warm-ups.
Through six games, the Bears gave up an average of 71 yards rushing. But they had given up 136 yards per game on the ground in the previous six games.
