ORCHARD PARK, N.Y. (AP) - Jacksonville running back Rashad Jennings was knocked out of the Jaguars game against the Buffalo Bills on Sunday after sustaining a head injury in the second quarter.

Jennings was injured following a 12-yard run with just under 14 minutes to go in the first half. After Jennings was tripped up, Buffalo linebacker Nick Barnett landed on him.

Jenning was able to walk off the field under his own power before being escorted to the locker room.

The Jaguars are already missing running back Maurice Jones-Drew because of a foot injury.

Jacksonville offensive lineman Mike Brewster hurt his hand in the first quarter, and left for X-rays. His return is questionable.
