Raiders’ Tracy Porter suffered a concussion on Monday night

Raiders cornerback Tracy Porter suffered a concussion during Monday night’s loss to the Broncos.

“It’ll be a big blow,” Raiders free safety Charles Woodson said, per CSNBayArea.com. “It’s a guy who is getting his chance, and each week he’s getting more comfortable. Terrelle did some good things, so it’ll be a tough blow for him and his development if he’s unable to shake it off and bounce back. We’ll see how that pans out.”

If Porter is unable to play this week against the Redskins,  rookie D.J. Hayden and Philips Adams will have to defend the outside.
