The Lions traveled to Minneapolis in week 6 to take on the Minnesota Vikings. In the first quarter, Detroit's misery continued as Orlovsky unintentionally ran out of the back of his endzone, giving the Vikings a safety.  In the second quarter, the Lions got the lead as kicker Jason Hanson got a 40-yard field goal.  In the third quarter, Detroit increased its lead as Orlovsky completed a 12-yard TD pass to WR Calvin Johnson.  However, Minnesota answered when QB Gus Frerotte completed an 86-yard TD pass to WR Bernard Berrian.  In the fourth quarter, the Vikings sealed the win when kicker Ryan Longwell nailed the game-winning 26-yard field goal. Dan Orlovsky's run out of the end zone for a safety topped the list of ESPN's Not Top 10 of 2008.
