Wawrinka rant earns Kyrgios suspended ban and $34,000 fine

Tennis badboy Nick Kyrgios has been handed a suspended ban and fine by the ATP for his lurid verbal attack on Stan Wawrinka.

In a statement on Monday, the ATP said it found 20-year-old Kyrgios guilty of "aggravated behaviour" and served him with a 28-day ban and $US25,000 ($A34,280) fine.

But both punishments will be waived if Kyrgios avoids any fines for verbal or physical abuse at ATP events over the next six months.

"Once the player has met those conditions the penalties will be formally dismissed," the ATP confirmed.

"If the conditions are not met the penalties will be invoked after any appeals process is exhausted."

Kyrgios made headlines around the world after crude remarks concerning Wawrinka's reported girlfriend, teenager Donna Vekic, during a match against the Swiss ace in Montreal.

Kyrgios, who was fined $US10,000 by the ATP for his courtside sledge at the time, issued a statement apologising for his remarks, insisting they were made "in the heat of the moment".

The ATP's head of rules and competition Gayle David Bradshaw said: "This incident was egregious and reflected poorly on our sport.

"Nick has expressed regret, and the best result would be that he learns a lesson from this incident and that he understands he is responsible to the Tour and to fellow players for both his actions and his words.

"It is with these factors in mind I feel he should have the opportunity to 'earn' his way out of additional sanctions."
