This came after the Adria Tour had multiple positive tests including Grigor Dimitrov and Borna Coric and Kyrgios tweeted:
"Boneheaded decision to go ahead with the 'exhibition', speedy recovery fellas. But that's what happens when you disregard all protocols. This IS NOT A JOKE."
He also retweeted Mitchell Krueger's tweets which said "Stellar leadership #ifyouknowyouknow" as well as saying himself "Congratulations. Such leadership" at an image put out by The Tennis Podcast of Goran Ivanisevic on court revealing the cancellation of the tournament.
