After suffering a brutal helmet-on-helmet collision from Falcons safety Keanu Neal, Redskins tight end Jordan Reed was forced to leave Thursday's preseason matchup with concussion-like symptoms.

The Redskins announced in the fourth quarter that Reed would be out for the remainder of the game, being evaluated for a possible concussion. Head coach Jay Gruden confirmed that Reed was in the concussion protocol during his post-game press conference.

"He developed concussion symptoms, and they went in the normal protocol," Gruden said. "He was symptomatic. We followed the protocol, and here we are."

When Neal delivered the hit on Reed, No. 86's helmet flew off. Initially, Reed seemed to be okay. He spun the ball after the play, celebrating the first down, and continued to play in the game.

It wasn't until several minutes later that the tight end started to feel the concussion-resembling symptoms.

"Right after halftime a little bit," Gruden said on when the tight end first started noticing them. 

Should Reed have a concussion, it would be the seventh confirmed concussion of his career, matching the amount of NFL seasons he's played. 

Gruden was later asked whether the hit should have warranted more than just a 15-yard unnecessary roughness penalty. 

"They got the 15-yard penalty and no ejection, I didn't notice it being that bad," he said. "I'll have to go back and watch it. We got the flag."
