Washington won against Dallas 25-3 Sunday, bringing both teams to 2-5 on the season, tying them for second place in the NFC East standings. Philadelphia leads 2-4-1.
Andy Dalton started at quarterback after replacing injured starter Dak Prescott hoping to turn things around.
But Dalton walked off the field late into the third quarter after taking a vicious hit from Washington linebacker Jon Bostic. He has a concussion and will be out for the rest of the game.
The hit occurred on a third-down play with 6:32 left in the third quarter. Dalton scrambled up the middle on 3rd-and-10 and as he slid to the ground, Bostic lowered his helmet and hit Dalton’s helmet squarely.
Dalton appeared to be knocked unconscious momentarily. Bostic was assessed with a personal foul and ejected from the game.
