Under NRL rules, the salary cap auditor will consider the following three points before making a cap exemption ruling:
• “The Player, at the time of termination, was diagnosed as medically unfit to currently continue to train and play elite level contact sport and was medically unable to ever return to play elite level contact sport due to the current level of disability or the significant risk of further disabling injury as a result of playing elite level contract sport;
• "The Player, had no similar injury or medical condition to that area of the body that either has or could reasonably be predicted medically to lead to a degenerative condition of that area of the body prior to signing his last NRL contract or if the players contract was signed more than 24 months previous within the last 24 months unless an unrelated single event has resulted in rapid deterioration of this condition; and
• A single event that caused the injury could be identified.”
