ARLINGTON, Texas -- Detroit Lions wide receiver Amon-Ra St. Brown has been ruled out in the first quarter of Sunday's game against the Dallas Cowboys with a concussion.
After catching a short-left pass from quarterback Jared Goff, St. Brown took a hit from Cowboys linebacker Anthony Barr and shook his head after the play.
An official flagged him immediately and St. Brown was evaluated in a blue medical tent before being taken to the locker room with no helmet. He was then ruled out for the game.
