That means that he is a mere 21 yards from wrapping up a nice Christmas present to Packers fans: 10,000 career yards. Could there be a better Christmas present than 21+ yards against the Bears in a sound drubbing of the Monsters of the Midway? He will be just the 36th person to have achieved the 10,000 yard mark. What's more, he will be only the 7th player to play his whole career with a single franchise & eclipse 10,000 rec yards:

The others being:
Marvin Harrison: 14,580 (Ind Colts)
Steve Largent: 13,089 (Sea Seahawks)
Hines Ward*: 12,027 (Pit Steelers)
Michael Irvin: 11,904 (Dal Cowboys)
Reggie Wayne*: 11,529 (Ind Colts)
Steve Smith*: 10,183 (Car Panthers)

* are players who are still active, though I can't imagine Hines Ward playing in anything but Black & Gold.

In addition to the three active players on that list, there are only 3 active players who have more career yards:
Tony Gonzalez: 13,289 (KC Chiefs, Atl Falcons)
Derrick Mason: 12,061 (Ten Titans, Bal Ravens, NY Jets, Hou Texans)
Chad Ochocinco: 11,044 (Cin Bengals, NE Patriots)
