Redskins tight end Jordan Reed is in concussion protocol after taking a vicious helmet-to-helmet hit in the second quarter of Thursday's preseason game in Atlanta.
"I think on that hit, he developed concussion symptoms," Gruden said. "They went into normal protocol and he was symptomatic, so we followed the protocol and there we have it."
"You know, you stand up here all the time and you start to worry about these injuries all the time," Gruden said. "These guys gotta go out and play football. They gotta practice. And it's unfortunate. Hopefully he'll be okay. I just talked to him. We just gotta go through the process, though.
