Novak Djokovic‘s mid-match retirement from the semifinal against Alexander Zverev at the Australian Open sparked controversy. He was booed by the crowd at Rod Laver Arena when he was leaving the court,

Novak Djokovic’s quest for a record 25th grand slam title has been cut short at the Australian Open after he stunningly retired from his semifinal match due to a left leg injury.

Former Serbian tennis star Viktor Troicki says the Australian Open crowd booing an injured Novak Djokovic was a plain disrespectful and disappointing move. Moments after Alexander Zverev won the first set 7-6 (5) which lasted an hour and 21 minutes, the record 10-time Australian Open winner walked to the net and retired.
