Hoping to rebound from their overtime loss to the Titans, the Packers flew to the Hubert H. Humphrey Metrodome for a Week 10 NFC North rematch with the Minnesota Vikings.  In the first quarter, Green Bay trailed early as Vikings QB Gus Frerotte completed a 3-yard TD pass to WR Sidney Rice.  The Pack would respond with RB Ryan Grant getting a 1-yard TD run.  In the second quarter, Minnesota answered with former Packer kicker Ryan Longwell getting a 54-yard field goal, along with back-to-back safeties.  The first one came when QB Aaron Rodgers committed intentional grounding in his own endzone, while the second one came when Rodgers was sacked by Viking DE Jared Allen.  Green Bay closed out the half with kicker Mason Crosby getting a 47-yard field goal. In the third quarter, Minnesota increased their lead as Frerotte completed a 47-yard TD pass to RB Chester Taylor.  Afterwards, the Packers took the lead as safety Nick Collins returned an interception 59&#160;yards for a touchdown, along with CB-KR Will Blackmon returning a punt 65&#160;yards for a touchdown.  In the fourth quarter, Crosby increased the Pack's lead with a 40-yard field goal.  However, the Vikings got the lead as RB Adrian Peterson got a 29-yard TD run.  Green Bay tried to make a comeback, but Crosby's 52-yard field goal attempt sailed wide right.
