Nelson injured his hamstring on the second drive of the game. Lang hurt his ankle in the second quarter.
The loss of Nelson comes just as Green Bay's receiving corps was getting back to full strength. No. 1 receiver Greg Jennings was active Sunday for the first time since Sept. 30. And Lang's injury is a costly loss for an already thin offensive line. Lang started the first nine games at left guard before moving over to right tackle after Bryan Bulaga suffered a season-ending hip injury. Undrafted rookie Don Barclay replaced Lang.
