Nick Kyrgios is in trouble with tennis authorities yet again following his withdrawal from the match against Steve Johnson during the Shanghai Masters yesterday.

The 22-year-old Australian had apparently said that if he lost the first set against Johnson he would withdraw from the match.

The 13th seed suffered a penalty for obscenities when he was heard to say that he would walk off court if Johnson won the tie-break.

Shanghai and Kyrgios have a controversial history to say the least.

This time last year, he was banned for seven weeks and fined £20,560 for ‘lack of best efforts’ in his 6-3, 6-1 defeat by Mischa Zverev.

Last year, the then world number 14 said he was sorry that his season ended the way it did and that he respected the decision by the ATP.

"I regret that my year is ending this way. I do understand and respect the decision by the ATP,” he said.

"The season has been a long one as I battled several injuries and other challenges towards the end of the summer.

"My body finally just gave out in Shanghai both physically and mentally.

"This is no excuse, and I know very well that I need to apologise to the fans."

You’d hope that the lesson had been learnt following his seven-week ban, but once again at the same tournament, Kyrgios has found himself on the wrong side of the law and on the end of a £7,000 fine.

Not only that, he's also been docked £16,000 in prize money for unsporting conduct.

"Guys, I want to apologise to the fans in Shanghai and those that watched around the world on TV today,” the 22-year-old said on social media.

"I've been battling a stomach bug for the past 24 hours and I tried to be ready but I was really struggling on the court today which I think was pretty evident from the first point.

"My shoulder started to hurt in the practice which didn't help either and once I lost the first set I was just not strong enough to continue because I've not eaten much in the past 24 hours.

"I'm hoping to be okay for the doubles and will make a decision tomorrow morning, hopefully off of a good night's sleep which I didn't get last night!

"I'm gutted to be honest to be honest as I was keen to keep the good momentum that I built in Beijing going and finish the year strong. I'll do what I can to make sure I do."

Different year – same excuses.
