After the 2004 World Championship, King became involved in a tense battle with Quinten Hann after his friend Andy Hicks eliminated Hann in a controversial first-round clash. Hann had been making provocative gestures during the match and after Hicks took victory, the two players had an altercation, with an angry Hann squaring up to Hicks. Upset by Hann's behaviour, King challenged the Australian to a boxing match, for which King was later criticised, as Hann's behaviour had already put the game into disrepute. Nevertheless, the bout went ahead and Hann controversially won the fight on a points decision.
