Jarrad Hickey was involved in great controversy during the final round of the 2009 NRL season, in Hazem El Masri's farewell game against the New Zealand Warriors. Hickey broke through the Warriors defence with El Masri in support and ran almost fifty metres to score. He also ignored two opportunities to offload the ball, denying El Masri the chance to score a try in his final home game. Hickey later revealed that he was keen on avoiding the dreaded post-season nudie run for all those without a try for the year. He was also dubbed "largest player in league history" by Rugby League guru Phil "Gus" Gould.
