"It has been almost four years since the Green Bay Packers offense has gone into a game without wide receiver Greg Jennings.

It was the end of the 2007 season and the Packers had home-field advantage all wrapped up going into the final week. Jennings had a slight ankle sprain.

This week the Packers will be without Jennings again.

It will mark the first time since Week 2 of that '07 season that they have not had their top receiver available in a game where something was on the line. A victory over Kansas City on Sunday would keep the 13-0 Packers perfect and also clinch home-field advantage for the playoffs.

Jennings suffered a medial collateral ligament sprain in his left knee against Oakland on Sunday and will be out until the Packers play their first playoff game the weekend of Jan. 14-15."
