After Triple H decked Kevin Nash with a sledgehammer in the main event at Night of Champions, Michael Cole, who had lost his voice, was seen writing something on a piece of paper and showing it to Jerry Lawler. Lawler then showed the paper to members of the WWE crew who then ran to the backstage area.
After the main event, Nash stayed on the floor until someone came from the back to tend to him. The "X" symbol was thrown up and other officials came to check on Nash, even Jerry Lawler. Nash finally staggered to his feet and was helped to the back by officials.
