After Further Review is a deeper look at plays or stats the day after Vikings games.

The importance of "clean hands" became apparent in Minnesota's 17-3 loss to Detroit Sunday at TCF Bank Stadium.

The Vikings forced a punt by the Lions late in the second quarter. Marcus Sherels returned the ball 14 yards before George Johnson hit him and forced a fumble that Lions LB Tahir Whitehead recovered.

The play, however, was wiped from existence because of the rule regarding the double foul prior to change of possession or "not clean hands" rule.

Officials flagged Minnesota's Shaun Prater for holding, and flagged Detroit's Julian Stanford for illegal use of hands. The fouls occurred before the fumble, and because the Lions did not have clean hands on the play, they did not receive the ball.

The penalties offset, and the down was replayed from the same spot.

Detroit's Sam Martin booted the ball 47 yards before it landed out of bounds.

Two plays later, however, Whitehead showed good hands in corralling a pass that bounced off Matt Asiata for the first of Whitehead's two interceptions of the game.
