Knocked unconscious in the first game of the 2014 season, Fulton was unable to return to the field. Wests Tigers, who were winning at the time, went on to suffer a defeat. Fulton later said, "I've been concussed that many times that I'm probably beyond it now, to be honest. You get paid well and I think everyone knows that there's going to be head knocks involved and if you don't want to cop a head knock you don't play really." Fulton announced his immediate retirement from the game on 10 July 2014, after receiving further concussions which had caused short-term memory loss and confusion. While told that the effects of the head-knocks may reversed, he was also warned he risk permanent damage if he suffered any more. "Rugby league has given me everything, to be honest. It's up there with the best thing that's ever happened to me in my life," he said.
