Novak Djokovic suffered an untimely wrist injury during his 6-4,6-4 loss to Alex de Minaur in a United Cup play off game..
This was the Serb’s first defeat in Australia in 43 matches.
With the Australian Open only two weeks away this will be a major concern for the current Melbourne title holder.
The World No.1 previously called for action during the Davis Cup Finals about the week in week out change of balls on the tour.
