Australian tennis star Nick Kyrgios defeated young French player Antoine Hoang during the second round of the US Open, but not before clashing with the umpire about a three-word slogan hidden on his shirt collar.
During the warm-up, Kyrgios' wore his usual white shirt but with the words 'Just Do You', a play on Nike's iconic trademark 'Just Do It', emblazoned on the back of his collar.
The umpire instructed the Aussie tennis star to change his shirt, as he claimed the slogan was a dress code breach. However, Kyrgios got angry from his request and demanded to see the rule book.
"I wanna see the rule. I wanna see the rule. I'm not going to play until you show me the rule," Kyrgios reportedly said.
When no rule book was brought to him, Kyrgios reluctantly agreed to play with his collar down.
The delay to the match and the argument did not affect Kyrgios as he put on an impressive performance, claiming victory in straight sets, 6-4, 6-2, 6-4.
Nick Kyrgios will play Russian tennis player, Andrey Rublev in the third round of the US Open.
