Medvedev, 25, will kick off the singles proceedings in the tournament during the afternoon session on the opening day on Sunday against Hurkacz.

Djokovic thrashed Medvedev in straight sets to win his ninth Australian Open title in February while the Russian returned the favour in September to deny the Serbian a historic calendar Grand Slam and win his first major.
