Favre then looked to pick up a big chunk of yards, hitting a sliding Antonio Chatman for 21 yards to the Jaguars' 23. The Packers called a timeout, with 1:18 left in the half, to set up the next salvo.
Instead, in the chess match that is football, Jack Del Rio delivered checkmate. Packers coach Mike Sherman called a handoff to Ahman Green, but Jaguars coach Jack Del Rio dialed up a corner blitz by Kiwaukee Thomas.
Thomas, who was lined up over slot receiver Robert Ferguson, broke to the line of scrimmage just before the snap. Ferguson reacted too late to make the block. A split-second after Favre put the ball in Green's belly, Thomas put his shoulder into Green. It appeared Green took his eye off the ball as he saw the blitzing Thomas. The ball fell to the ground and was recovered by Jaguars linebacker Daryl Smith.
"They had the perfect blitz on for that play and we hadn't seen that blitz too many times in that personnel package," said Favre. "As I came back to hand the ball off, the guy is right there and obviously Ahman felt him there, too. They timed it up perfectly."
The turnover was one of five on the day by the Packers as the Jaguars pulled off a 28-25 upset victory.
