Here’s a look at a key matchup heading into the Week 11 rematch between the Vikings and Packers at the Metrodome.

Vikings WR-KR Percy Harvin vs. Packers CBs Charles Woodson and Tramon Williams and Green Bay’s special teams

Harvin, a dynamic, all-purpose weapon with 4.41 speed and tremendous yards-after catch ability, is hardly the picture of health with a tender ankle and migraine headaches that come and go with regularity. But with both Sidney Rice and Bernard Berrian looking like major long shots for the second game between Minnesota and Green Bay this season and the Vikings’ season teetering on the edge of oblivion, it’s likely Harvin will make every effort to give it a go. He did practice on a limited basis Wednesday.

Harvin, who has gained 13.3 yards per catch this season, has been productive as of late, gaining at least 64 yards receiving in each of his last four games, including 5-65 in the first game against Green Bay a month ago, in addition to a 17-yard TD run. A threat to go the distance every time he touches the ball, he also had a 95-yard kickoff return for a TD earlier this season and returned six kickoffs for 151 yards (25.2 average) against the Bears last week.

Woodson and Williams figure to share coverage on Harvin and are both coming off strong efforts in the Packers’ last game against Dallas. They tied for the team lead with five tackles each against the Cowboys, with Woodson also registering a sack and a forced fumble. Williams has played at a Pro Bowl level all season.
