Packers LB Kampman taken for X-rays on knee

Packers linebacker Aaron Kampman left on a cart for X-rays on his left knee midway through the third quarter of Green Bay's game against San Francisco. Kampman was rushing against right tackle Adam Snyder when he went down and clutched his knee. Alex Smith overthrew Isaac Bruce in the end zone on the play. Kampman walked off the field with a limp and went straight to the trainer's table behind the Packers' bench. Moments later, he walked to a cart and was taken to the locker room for X-rays. The team said Kampman's return was questionable. Kampman sat out last week's game against Dallas with a concussion, the first game he's missed due to injury since 2003.
