Andy Murray made a first-round exit from the Brisbane International as Grigor Dimitrov came from behind to win in three sets.
Bulgarian second seed Dimitrov triumphed 4-6 7-5 6-2 to progress at the season-opening tournament.
The defeat is a setback for Murray’s preparations for the Australian Open, which starts on 14 January.
It comes after the Briton said the 2024 season could be his last on tour if he is “not enjoying it”.

The 36-year-old struggled with a shoulder injury in the latter months of 2023.
Playing in his first competitive singles match since October, Murray came out on top of a tight first set that went with the serve, sealing the opener on its only break point after an error-strewn Dimitrov service game.
