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.
Jennings 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.
Bills receiver Stevie Johnson left in the third quarter because of a left hamstring injury, and Buffalo starting offensive lineman Chris Hairston was carted off in the third quarter because of a right ankle injury.
Jacksonville offensive lineman Mike Brewster hurt his hand in the first quarter, but was able to return to start the second half.
