The Scot, whose movement was laboured, held serve only once and was trailing 6-1 4-1 when they called it a day.

Three-time Grand Slam champion Murray, who missed most of last season after hip surgery, has tumbled down the rankings to 230th.

Murray has lost four times to Serbia's Djokovic in Australian Open finals.

The practice set and a half - curtailed because another practice match was booked to follow them - was watched by around 2,000 people on the Margaret Court Arena show court at Melbourne Park.

Murray, 31, who has played only 12 matches since returning from surgery last year will find out his first-round opponent later on Thursday.

He has used his protected ranking to enter the first Grand Slam of the year but will not be seeded and so could face a top-ranked player early on.

Murray's first tournament since September ended last week with a second-round defeat by Russian world number 16 Daniil Medvedev at the Brisbane International.

The Australian Open starts on Monday and runs until 27 January.
