Aleksandar Vukic has taken top-ranked Brit Jack Draper to the brink in the third round of the Australian Open before being edged in a fifth-set tiebreak.

Kokkinakis has been struggling with a pectoral injury for some time, and was forced to withdraw from the Adelaide International last week. He managed to win his first-round singles match at the Australian Open, before suffering a heartbreaking five-set loss in the second round.

Nick Kyrgios raged at an Australian Open umpire after his doubles partner Thanasi Kokkinakis was given a code violation for hitting the ball out of play. Kokkinakis was pulled up in the first set against Aleksandar Vukic and James Duckworth for launching the ball into the stands in frustration, before he and Kyrgios later retired.

The apologetic Aussie was plainly ‘shattered’ to tell his great mate Nick Kyrgios it was all over. Thanasi Kokkinakis’ dream of repeating his stunning Australian Open doubles success with Nick Kyrgios has been dashed by his debilitating pectoral muscle injury.

Kokkinakis was hampered by a long-standing pectoral injury as he went down 7-6 (7-3) 3-6 6-3 5-7 3-6 to Jack Draper in a four-hour-and-35-minute heartbreaker. Speaking after the match, Kokkinakis said he wouldn't even be able to lift his right arm to serve on Thursday night.

The 29-year-old’s Australian Open return was short-lived — and he warned it could be his last singles match in his homeland.

Nick Kyrgios has fuelled further discussion about the future of his tennis career as he said that he was "weighing up his options".

Both Kyrgios (strained abdominal muscle) and Kokkinakis (right shoulder trouble) came into the match dealing with physical issues.
