Question: what was significant about dermott breretons performance in the 1989 grand final against geelong
Answer: In one of the toughest grand finals in the league 's history , Brereton was lined up at the centre bounce by Geelong Football Club 's Mark Yeates and hit with a solid shirtfront . Severely winded and concussed , he was attended to by trainers . He began to vomit before jogging back into the play . Only minutes later in the game , he marked and kicked an inspirational goal . He would finish with three goals in a game that Hawthorn would win by six points . He was later diagnosed with broken ribs .
