A diver attempting a 2 1/2 inward dive on a 3-meter board hits her head on the end of the board. She lands on her face in the water, is briefly submerged, but floats quickly to the surface. She is conscious but disoriented; she has a bump on her forehead but is not bleeding. A teammate nearby jumps immediately in the water and, using cross-chest technique, tows her about 10 feet to the side of the pool. The athletic trainer is concerned about both a head and neck injury. What precautions should be taken when removing the injured athlete from the pool?
