Novak Djokovic said Friday there was a chance he may have played his last Australian Open after retiring with a muscle tear in the semi-finals to leave his bid for a record 25th Grand Slam crown in tatters.
The 37-year-old's upper left leg was again heavily taped after hurting it in the quarter-finals and the Serb called it quits after losing the first set 7-6 (7/5) to Alexander Zverev.
