Following their home win over the Falcons, the Vikings flew to Ford Field for a Week 2 divisional match-up with the Detroit Lions. After a scoreless first quarter, Minnesota trailed early as Lions quarterback Jon Kitna completed a 9-yard touchdown pass to wide receiver Roy Williams. The Vikings tied the game with a 1-yard touchdown run from quarterback Tarvaris Jackson. However, Detroit retook the lead with kicker Jason Hanson's 30-yard field goal. In the third quarter, the Lions increased their lead with a 7-yard touchdown pass from J. T. O'Sullivan - who was in for the injured Kitna - to Calvin Johnson. Minnesota tied the game through a 32-yard field goal from Ryan Longwell and a 9-yard fumble return touchdown from defensive end Ray Edwards. After both teams failed to score in the fourth quarter, the Vikings received the ball first to begin overtime. However, nine plays into the Vikings' drive, Detroit recovered a fumble by backup Vikings quarterback Brooks Bollinger for the game's 10th overall turnover, allowing Hanson's to kick a 37-yard, game-winning field goal.
