Rookie cornerback David Amerson said he expects to play in the Washington Redskins’ game Sunday against the Chicago Bears at FedEx Field.

Amerson suffered a concussion during last Sunday night’s loss at Dallas.

As he left the practice field Friday, he said he would be surprised if he doesn’t play Sunday.

Amerson was to be listed as questionable on the official injury report and he’s awaiting final clearance from doctors to play Sunday under the NFL’s procedures for treating players who suffer concussions.

Coach Mike Shanahan said he would expect Amerson to play Sunday if the cornerback passes his concussion tests Saturday.

Amerson said he has not been experiencing concussion symptoms in recent days.

“Everything is fine with me,” Amerson said, “so I think I should be ready to go…. I feel fine.”

Amerson said he won’t allow the injury to affect the way he plays, even with the attention given in recent years to the possible long-term ramifications of head injuries.

“It’s part of football,” he said. “You can’t let it put any fear in your heart or anything like that. You’ve still got to go out there and give 100 percent effort. So I won’t let that affect anything. … It might be in the back of your head a little bit. But you can’t really just put that front and center. You can’t think about that all the time because then, again, you’ll start playing cautious and kind of timid toward things. You’ve got to understand the game, that’s what you’re at risk [for]. You’ve got a risk of getting hurt in any way. So you’ve got to go out there knowing that anything can happen but still just give it your all.”

Tight ends Fred Davis (ankle) and Logan Paulsen (knee), center Will Montgomery (knee), linebacker Brandon Jenkins (ankle), cornerback Jerome Murphy (ankle) and defensive tackle Chris Neild (calf) are to be listed as probable on the injury report.
