Ten-time Australian Open champion Novak Djokovic has been booed off the court by some sections of Rod Laver Arena audience after sensationally retiring hurt from his semi-final against Alexander Zverev on Friday after losing the first set.

The Serb suffered an injury to his groin area in his quarter-final against Spain’s Carlos Alcaraz and took to the court with both dark tape and a white bandage enveloping his upper thigh.

He revealed afterwards he had not hit a ball since Tuesday’s match, and the pain proved too much. “I did everything I possibly can to basically manage the muscle tear that I had,” Djokovic said.

“Medications, and this strap, and the physio work helped to some extent today, but towards the end of that first set, I just started feeling more and more pain, and it was too much to handle for me at the moment. So, yeah, unfortunate ending, but I tried.”

When he was asked whether this was his last Australian Open, the 37-year-old was non-committal. “I don’t know, there is a chance. Who knows? I’ll just have to see how the season goes,” he said.

“I want to keep going, but whether I’m going to have a revised schedule or not for the next year, I’m not sure. I normally like to come to Australia and play, and I’ve had the biggest success in my career here. So if I’m fit, healthy, motivated, I don’t see a reason why I wouldn’t come, but there’s always a chance.”

Despite the ailment, he looked close to his best across 81 minutes in a taxing first set, won narrowly by the German in a tie-break 7-5. But after missing a volley to hand his opponent Zverev the set, the Serb walked over to the other side of the court and embraced the second seed.

It triggered boos from some sections of the crowd, who had paid hundreds of dollars for tickets.

Zverev criticised those who booed Djokovic in his on-court interview after the match. “The very first thing I want to say is, please guys, don’t boo a player when he goes out with injury,” he said, prompting applause from a majority of the crowd.

“I know that everybody paid for tickets and everybody wants to see, hopefully, a great five-set match and everything. But you’ve got to understand, Novak Djokovic is somebody that has given this sport, for the past 20 years, absolutely everything of his life.”

Former Australian tennis player and broadcaster John Millman criticised the crowd’s reaction on social media. “Novak getting booed off is a disgrace. Classless,” he said.

It was a jarring end to another remarkable tournament for Djokovic, who knocked out the highly fancied third seed Alcaraz in the previous round. Earlier in the tournament, he refused to do an on-court interview after he felt he was disrespected by Channel Nine reporter Tony Jones in a television cross.
