"Towel around his neck, wide receiver Greg Jennings gave the crowd a thumb's up and was carted to the locker room. The Green Bay Packers have lived these nightmare scenarios before.

Midway through their 46-16 whipping of the Oakland Raiders, Jennings twisted his knee between a pair of defensive backs.

"It didn't look very good, so we'll see what the MRI says tomorrow and hopefully, you know, we got a bye wrapped up, so he really has close to five weeks before the next game, or our playoff game," quarterback Aaron Rodgers said. "So hopefully we can get him ready for that."

The most likely scenario seems to be a torn medial collateral ligament, which does not require surgery and generally requires two to six weeks of recovery. Until Jennings undergoes an MRI, the extent of the injury is unknown."
