Niles Paul has suffered a concussion before, but nothing compared to what the Redskins tight end experienced in Week 8 against the Dallas Cowboys. Paul was attended to on the field for several minutes in the first quarter after running back Rob Kelley scored on a one-yard touchdown run. He walked off the field and straight into the locker room, where he was officially diagnosed with a concussion. Paul didn’t return in that game, didn’t practice the following week and missed Sunday’s victory over the Seattle Seahawks as he sat at home to relax and “let my brain settle down.” “I don’t remember anything,” Paul said. “I don’t remember walking off the field. I barely remember walking out the stadium. I’ve never been concussed like that, so it was a bit scary for me.” Paul, who returned to practice on Wednesday as a limited participant, said he has re-watched his goal line collision with Cowboys linebacker Sean Lee that caused the concussion. Serving as the team’s fullback, Paul ran right behind guard Shawn Lauvao along the right hash, dropped his head and tried to deliver a blow. As Kelley crossed the goal line, Paul’s helmet popped off. He was unresponsive as tight end Jordan Reed approached him. The offense’s celebration ended abruptly as Washington’s training staff ran onto the field.
