But he told The SportsXchange on Thursday the concussion problems let on sooner than he told anyone and he "was in a bad spot for a long time."
"I think I had had a concussion two weeks before, but I didn't tell nobody so when I took a shot to the side of my head against the Eagles it made it worse," Reed said. "I was in a bad spot for a long time. I didn't know if they would ever go away, but I'm past it now."
That's ... terrifying. The good news is, per coach Jay Gruden, Reed "has had no setbacks."
"I think [Jordan] has had no [set]backs from his concussion, knock on wood," Gruden said. "We have, obviously, one of the more talented young tight ends in the league. He's going to be a great guy up in the middle of the field. If people want to crowd DeSean or crowd Pierre, he's a guy that's very much needed in the passing game. [Jordan] is obviously a force in the passing game. We've got to work him a little (on) being more stout in the running game."
But he needs to stay healthy. And he definitely needs to make sure he doesn't hide any more concussions.
