HOUSTON -- Houston Texans starting cornerback Kevin Johnson left Saturday's preseason game against the San Francisco 49ers with a concussion and will not return.
Johnson sustained the concussion when he landed hard on the turf while defending a pass from Jimmy Garoppolo to Marquise Goodwin on the first series of the game. The cornerback was down on the ground while he was checked out by the training staff after he landed on the sideline. Johnson was eventually able to walk off the field under his own power and was taken to the locker room.
