Reed did not practice Wednesday as he's now being evaluated for a concussion.
It's an especially concerning development for Reed, who has suffered five concussions from 2011 to 2015 dating back to his college career at Florida.
Reed has played almost every snap for the Redskins' offense so far this season, leading the team in receptions (33) and receiving yards (316) while hauling in two touchdown catches, tied with Jamison Crowder for most by a Washington player to date. If doctors determine he has a head injury, Reed will be placed in the league's protocol and his status for Sunday against the Eagles would be in serious doubt.
NOTES: Linebacker Su'a Cravens (concussion) and cornerback Bashaud Breeland (ankle) were limited participants in practice for a second straight day.
Cravens, 21, said in a video: "Due to my concussion my eyes have lost the memory to keep track of moving objects, so I have to wear these for the rest of my life". The coach added that Washington is taking the "cautious approach". "We just want to make sure we take all the right steps". We obviously want him to get well.
NZ tourist died fleeing from Tostee: trial
Collyer was giving evidence on the first day of the trial of Gable Tostee, who has pleaded not guilty to the murder of Wright. Earlier , the court also heard Tostee called his father after Wright fell to her death and told him the pair had had sex.
"As a friend, I'm extremely concerned for his health", Williams said.
"He's a very talented player, he's shown that", Cousins said of Reed.
Last year, Reed suffered a concussion early in the season that kept him out for two weeks, but in 2013, he suffered a far more severe one that ended his season prematurely and forced him to see specialists. "He's shown that. We love to have our best players out on the field with us".
Reed isn't the only Washington player dealing with an injury. "We got talent at that position, so hopefully we won't feel the drop-off as bad".
