Novak Djokovic said he did 'everything I possibly can' to manage his injury before and during his Australian Open semi-final against Alexander Zverev. The 10-time champion retired hurt after losing the first set, and was booed off the court by some sections of the Rod Laver Arena. Djokovic suffered an injury to his groin area in his quarter-final against Spain’s Carlos Alcaraz on Tuesday.

The Serb took to the court on Friday with both dark tape and a white bandage enveloping his upper thigh. He revealed afterwards he had not hit a ball since his previous match, and the pain proved too much for him to play on after losing the first set on a tie-break. 'I want to keep going,' the 37-year-old added, but also admitted 'there is a chance' this could be his final appearance at Melbourne Park.
