The Vikings thought they had gotten off to a fast start when Percy Harvin took the opening kickoff back 103 yards for what appeared to be a Minnesota touchdown, but a block in the back by Marvin Mitchell negated the return. Both teams exchanged three-and-outs on their first possession, and the Vikings finally hit pay dirt the second time they had the ball.
Adrian Peterson started the drive off with a huge 27-yard run, and a big pass interference penalty on Jerome Simpson put the ball on the Arizona 13. Peterson took care of things from there, as he went in from 13 yards out (shown above) for a 7-0 Minnesota lead.
Arizona then put together a lengthy drive that put them into the Minnesota red zone, but Brian Robison sacked John Skelton and forced a fumble that was recovered by Kevin Williams, stopping the drive in its tracks.
That's where we stand after one quarter of play, ladies and gentlemen, with the Minnesota Vikings holding a 7-0 lead over the Arizona Cardinals at the Metrodome.
