Novak Djokovic's father could be banned from the Australian Open final as he awaits a decision from tournament organisers on his controversial interaction with Vladimir Putin supporters.
Djokovic is targeting a record-extending 10th Australian Open title in Sunday's showdown against Stefanos Tsitsipas in Melbourne.
But he might be without the support of his father on the Rod Laver Arena after footage emerged of Srdjan Djokovic at a pro-Russian demonstration on Wednesday.
