Novak Djokovic suffered an injury scare ahead of the Australian Open with a hamstring twinge forcing him to cut short a practice match with Daniil Medvedev.
The 21-time Grand Slam champion, who missed last year's Australian Open after being deported due to his vaccination status, played just one set against Medvedev before withdrawing.
Djokovic lasted a little under 40 minutes on Rod Laver Arena on Wednesday, in what marked his first appearance in Melbourne since being forced to leave the country last year.
The Serb, seeded No 4 for this month's major in Melbourne, initially tweaked his hamstring during his run to the Adelaide International 1 title last week.
