TEMPE, Ariz. - Three days ago, Arizona Cardinals starting defensive end Calais Campbell was placed on a stretcher and carted off the field in San Francisco.
He was experiencing numbness and tingling in his extremities following a fourth quarter collision with teammate Karlos Dansby while the two made a tackle.
Wednesday, Campbell stood in front of his locker confident he would be able to play against NFC West-leading Seattle in a little over 24 hours at University of Phoenix Stadium.
"This is a game you don't want to miss," he said. "I'm feeling good. I know my body. My body is feeling good, so that's all I'm really worried about is how I feel. If I had felt like I couldn't protect myself or go out there and play the game the way I'm supposed to I wouldn't go out there. It's all about how my personal feeling of my body and understanding it and just being true to myself."
Campbell practiced, albeit on a limited basis, the past two days.
"He's been fine," head coach Bruce Arians said. "Looks like he's ready to go."
Campbell, 27, is officially listed as questionable.
"That means that I got to go out there before the game (during warm-ups) and show (the training staff) that I'm ready to play, that's all," he said. "The biggest thing is being able to protect myself when I need to. That's the biggest thing. As long as I can prove that, I'm good."
Late Sunday night, Campbell checked out of Stanford Hospital after undergoing a CT scan and an MRI as a precautionary measure. He was back at the training facility only hours later in time for the team's morning meetings.
"I feel very similar to how I normally feel (on a Wednesday)," Campbell said after practice. "Any time you play a Thursday game coming off a Sunday game, your body doesn't really have enough time to recover like you want it to all the way. You don't really get a day off to just relax and take care of our body because you have to do work every day. I feel like I would normally feel before a Thursday game, in my opinion."
Should Campbell not play, third-year pro Ronald Talley would likely slide into the starting lineup.
The Cardinals though are hopeful they'll have Campbell's playmaking ability, especially against the Seahawks' dual-threat quarterback Russell Wilson and running back Marshawn Lynch.
There's also the need to erase the memories of the teams' previous meeting, a 58-0 loss in Seattle last December.
"It definitely keeps a bitter taste in your mouth," Campbell said. "That's one of those things where you don't want a bitter taste in your mouth. You always want to get that out of your mouth as quick as you can, so you always look forward to playing against a team like that again and try to redeem yourself.
"It's a good opportunity," he continued. "Primetime -- to go out there and try to redeem yourself."
