Ramon Foster Injury: Steelers LG out with possible concussion, Guy Whimper in vs. Raiders

The Steelers are off to a disastrous start at the Oakland Raiders, and it may have gotten a little worse.

Left guard Ramon Foster is out with a possible concussion during the second quarter with the Steelers trailing 14-3. Veteran Guy Whimper is in for him, as the Steelers have the ball in their own territory.

Whimper replaced right tackle Marcus Gilbert last week when he went down with a quadriceps injury. It's the only action he's seen this season.

Foster was a late addition to the injury report, the team listing a thumb injury and probable status for the Steelers' Week 8 game.

He suffered a biceps injury in the Steelers' Week 4 loss to Minnesota as well. Mike Adams and Cody Wallace are the other two active linemen for the Steelers in this game.
