Novak Djokovic has sparked fears that he might miss the Australian Open due to a hamstring issue which has hampered his preparations for the tournament.
The Serbian is due to the start his campaign at Melbourne Park by taking on World No.75 Roberto Carballes Baena tomorrow morning. However, the 21-time Grand Slam champion has cancelled his practice session for the second day running.
Djokovic continues to be hampered by the injury which he suffered at the Adelaide International earlier this month. The World No.5 has won nine Australian Open titles and if he can clinch victory again this year he would match Rafael Nadal's record of 22 major crowns.
