Nick Kyrgios is in the headlines for the wrong reasons once again, this time abusing a fan during an ATP event in Acapulco.
Kyrgios, who defeated world No.75 Dudi Sela, 3-6, 6-3, 6-3 on Wednesday, told a fan to "shut the f*** up," as he was about to serve.
The Aussie didn't stop there, mockingly waving at Sela's fans post match from his chair.
Sela then confronted Kyrgios, with the pair involved seemingly in a heated argument, before the umpire was forced to step in to diffuse the situation.
Kyrgios will face American Donald Young in the next round.
