Playing their first home game since mid-October, the Packers hosted their division rivals, the Minnesota Vikings. In the first half, the first career touchdown by Ryan Grant came on a 30-yard run and gave the Packers a 7-0 lead, and two field goals by Mason Crosby (a 39-yard field goal midway through the 2nd quarter and a 24-yard field goal at the end of the half) would provide all the first half scoring, as the Packers went to the locker room leading 13-0. In the second half, Brett Favre threw a pair of third-quarter touchdown passes, one to Donald Lee and one to Ruvell Martin (which was Favre's 200th TD pass at Lambeau Field), giving the Packers a 27-0 lead. With an additional Martin touchdown catch in the 4th quarter, the Packers shut out the Vikings 34-0, their first shutout of 2007. The Packers defense held Adrian Peterson to a season-low 45&#160;yards on 11 carries a week after he set the NFL single-game rushing record with 296&#160;yards against the San Diego Chargers. Grant became the first running back to reach the century mark against the Vikings this season, rushing for 119&#160;yards on 25 carries, his career best. With the win, the Packers improved to 8-1, which matched the best start to a season in Brett Favre's career (in 1996 and 2002). This game was the first time the Vikings had been shut out since 1991, and halted the Vikings' NFL-record run of 260 consecutive regular-season games with a point. The game was Green Bay's first shutout of the Vikings in 94 games of the rivalry. During the game, Favre became only the second NFL quarterback to throw for 60,000&#160;yards in a career. He now has 60,257 yards' passing in his 17-year NFL career, second only to Dan Marino's career passing record of 61,361&#160;yards. On November 15, 2007, the NFL announced Favre and running back Ryan Grant were voted the FedEx Air & Ground NFL Players of the Week for games played on November 11-12.  Favre has received the Fedex Air award four times this season. Coach McCarthy was voted the Motorola NFL Coach of the Week for games played on November 11-12, the second time he has received the award this season.
