The Kato - Sutjiadi duo was asked to return to the locker room prematurely after a ball was unintentionally sent into the cap of a ball collector. The referee initially decided to give a simple warning, arguing that the player had not done it on purpose, and that the picker had not been injured.
This provoked the ire of the Spanish-Czech duo, who had absolutely not seen the scene but vehemently demanded a disqualification. After long discussions between officials and hearing all the parties concerned, the sanction fell.
