An injured Novak Djokovic quit because of a torn muscle in his left leg after dropping the first set of his Australian Open semifinal against Alexander Zverev on Friday.
Djokovic lost the opener 7-6 (5) and immediately walked around the net to concede the match to Zverev and shake hands. Spectators booed as the 37-year-old Djokovic walked off toward the locker room, and he stopped, turned around and responded by giving two thumbs-up.
At his news conference, Djokovic said the pain in his left leg was “getting worse and worse.” He hurt it during his quarterfinal victory over Carlos Alcaraz on Tuesday night and wore white tape around his upper leg against Zverev.
