The Jets' seventh game was an interconference duel with the Packers. Punter Steve Weatherford made the game's most controversial decision in the first quarter, opting to attempt a fake punt and run for the first down on 4th and 18. Weatherford was stopped a yard short of the first down, giving the Packers ideal field position which eventually led to an early 3-0 Packers lead. "He does it on his own," Ryan said. "(The Packers) were caving that side down. This was something Steve did on his own. I don't think he realized we'd just been sacked. We told him before that it needed to be a manageable situation, not fourth-and-20 or whatever it was.". In a game where defense ruled, the Packers lead 3-0 at halftime.  The Jets challenged a Brad Smith fumble, and lost due to his knee not being down before losing the ball.  However, the Jets second challenge went to a jump ball, called an interception after Packers cornerback Tramon Williams ripped the ball out of Jerricho Cotchery's hands while they were both on the ground.  The play was controversially upheld, despite the fact that the receiver appeared to be down by contact.  With no challenges left, Mark Sanchez threw a ball to Dustin Keller that was ripped out of his hands and ruled an interception in the 4th quarter. The replay showed that Keller made the catch and was also down before losing possession, but with no challenges left the Jets were left with nothing. Green Bay took a 6-0 lead after the turnover. The Jets had two more chances to take the lead but had drives halted on 4th and longs. The Packers added on another field goal late to finalize a 9-0 win in the New Meadowlands Stadium. This marked the first time since 2006 the Jets were shut out.
