Ronnie O'Sullivan's first-round defeat in the 2025 UK Championship could yet prove to be pivotal as the current snooker season draws to a close.
The 49-year-old, who turns 50 later this week, lost 6-4 to China's Zhou Yuelong in York to bow out early from the tournament.
O'Sullivan had a number of chances to ensure what could have been a relatively comfortable victory, and played a poor positional shot on the green in the final frame to give Zhou the opportunity to secure a famous win.
'The Rocket' has opted for a part-time schedule this season, with the UK Championship being the first time he has competed in the UK since the World Championship in April.
He will now drop to number six in the world rankings, with the £250,000 prize money he earned from winning the UK Championship in 2023 dropping off his total points.

If results do not go his way, O'Sullivan could fall to as far as ninth in the rankings, with Shaun Murphy, Mark Selby and reigning world champion Zhao Xintong all able to overtake him.
His participation in the remainder of the tournaments this season is not under threat, as he is fifth in the one-year list that secures qualification for the World Grand Prix and Players Championship events.
Where O'Sullivan may have to think carefully is whether he participates in both of those events, given his part-time schedule.

He won the World Grand Prix in 2024, and is therefore defending another £100,000 in prize money this time around when that tournament takes place in March.
In 2024, he also reached the final of the Players Championship, banking another £60,000 in prize money.
Should O'Sullivan decide against playing all of those events, he could potentially run the risk of dropping enough ranking points to fall outside of the top 16 by the start of next season - if not, though a much more unrealistic scenario, by the time of the World Championship.
O'Sullivan has opted to play events in China this season, and the 2026 World Open in March offers a £175,000 winners' prize.

In effect, 'The Rocket' should be safe on both fronts as long as he enters enough events - but it may mean he needs to pick his tournaments with slightly more caution to avoid potentially having to qualify for certain events that are based on the two-year ranking system in the 2026/27 season.
He told BBC Sport's Shabnam Younus-Jewell that is unsure whether he will play in next month's Masters, which is a non-ranking invitational event.
"Obviously, he played better," O'Sullivan said. "A lot of bad mistakes, really. Basic ones. He deserved his victory today.
"I'm going to go for a run, go to the gym, have some nice food ... no, not really [decided about the Masters]. I'll go home, have a nice Christmas, and just see how I feel come January."
