Australian Open - 'I didn't know the rule!' - Toilet trip leads to warning for Filip Krajinovic
There was a very strange incident on day six of the 2021 Australian Open as Filip Krajinovic, who generally played the calm supporting role in a drama dominated by the perma-angry Daniil Medvedev in their third-round match at Melbourne Park. Krajinovic did not have a clue why he was suddenly given the warning.

The Russian forced his coach Gilles Cervara from the empty stands in Rod Laver Arena following several rants in his direction in a tempestuous feud, but perhaps the strangest incident was Krajinovic's code violation.
As the Serb left the court to go to the toilet, he neglected to put on his face mask, something for which he was immediately picked up on - quite rightly - by the umpire.

Krajinovic ranted with his coaches in his chair after receiving the formal warning, before pleading that: "I didn't know the rule!"
Medvedev will next take on American Mackenzie McDonald in the last 16 at Melbourne Park.

In completing the heated victory, the 25-year-old extended his winning streak to 17 matches and reached the fourth round.
Russia could end up with an Open era record four men in the last 16 of a Grand Slam, with Medvedev leading the charge of his compatriots.
