WATCH: Novak Djokovic leaves court for quick bathroom break shortly after the start of his match

Novak Djokovic left the court for a bathroom break after just five games in the opening set of his Australian Open first-round match against Roberto Carballes Baena.

After holding serve for a 3-2 lead at the end of a tough game in which he saved break points, Djokovic informed chair umpire Aurelie Tourte that he wished to go for a bathroom break. Tourte seemed to point out that a bathroom break was not within the rules but a regular break was possible within the changeover time, so the Serb rushed towards the restroom.

The chair umpire then conveyed a message to the nine-time champion that she would not wait for him before calling 'time', signaling the start of play.

"I will call time in 15 seconds," Tourte conveyed through her walkie-talkie.

As a few more seconds passed by, Tourte sent across another message.

"I am calling time now. You have 30 seconds to be back in play," the umpire declared.

Tourte was then heard calling out to someone that she would not hesitate in penalizing the Serbian star if he did not return within the allotted time. Djokovic eventually came back onto the court just in the nick of time, and avoided a penalty.
