Rookie tight end Jordan Reed continued to suffer from a headache Monday, nearly a month after suffering a concussion, according to Washington Redskins Coach Mike Shanahan.

“We brought him in on Saturday and he still had a headache [and] had one today as well,” Shanahan said Monday at Redskins Park. “So we’ll take a look at him each day. He’ll go through the protocol for a concussion and hopefully one day he’ll wake up and say, ‘Hey, I feel good. I’m ready to go.’ ”

Reed has missed the Redskins’ past four games since suffering a concussion during a Nov. 17 loss at Philadelphia.

“Once you get a concussion and you get treated accordingly, we just evaluate him every day,” Shanahan said. “I’ve asked these doctors before with different sports, ‘How long do this occur? How long has it occurred?’ Some doctors will tell me that it could be two or three months. It’s not just two or three days that I’m used to dealing with football players. … I’ve talked to a couple of our doctors and they said in soccer they’ve seen it go for two or three months.”

Reed remains subject to the NFL’s procedures for treating players who suffer concussions and must be cleared by an independent neurologist to practice and play. Shanahan said Monday that Reed has been evaluated by specialists.

Last week, Shanahan said there had been no decision made to withhold Reed from all of the team’s remaining games. The Redskins have only two games left, at home Sunday against the Dallas Cowboys and Dec. 29 against the New York Giants on the road.
