Ronnie O’Sullivan was targeting a record-extending ninth UK Snooker Championship title in York – but lost to Barry Hawkins in the first round.
World No 1 Judd Trump takes on Neil Robertson in a blockbuster opener on Tuesday.
Robertson, a three-time winner of the UK Championship, had to come through qualifying after dropping out of the world’s top 16.
Trump has won the Shanghai Masters and Saudi Arabia Masters this season, while he has also been runner-up in the Xi’an Grand Prix and Northern Ireland Open, beaten in both of those finals by reigning world champion Kyren Wilson.
The 2024 UK Championship final will be held on Sunday December 1
