The prospect of the World Snooker Championship proceeding without Ronnie O'Sullivan has rarely seemed so tangible. For more than three decades since turning professional in 1992, the veteran competitor has been a permanent fixture among the elite players who receive automatic entry to the sport's marquee event at the Crucible Theatre. Now, however, that status is facing a genuine threat.

Currently positioned 13th in the world rankings, the seven-time world champion is fighting to protect his place within the top 16. His recent form has done little to secure his ranking, highlighted by a first-round exit at the Northern Ireland Open. This followed an early departure in Shenzhen, meaning his only notable run during the current season came at the Wuhan Open, where he reached the semi-finals.

O'Sullivan has accumulated £513,750 in ranking event earnings over the past two years. That figure keeps him ahead of Ali Carter in 16th place and Zhou Yuelong just outside the cutoff at number 17. While this cushion provides some immediate security for the upcoming World Championship in May, the longer-term outlook is far more complicated.

A significant portion of O'Sullivan's current ranking total stems from a runner-up finish at the Saudi Arabia Masters in August 2025, where he collected £200,000. Although that sum remains valid through the 2027 World Championship, it will drop off his record early in the 2027-28 season. The challenge is compounded by the fact that the lucrative tournament in Jeddah was canceled in April, meaning he cannot replicate those earnings in the future. Consequently, solid performances will be required over the next year and a half to safeguard his automatic qualification for the 2028 tournament.

Compounding the ranking pressure is O'Sullivan's selective tournament schedule. In recent years, he has frequently withdrawn from events, citing health and well-being priorities. His appearances have largely shifted toward Asia, with his recent match in Belfast marking his first non-Triple Crown ranking appearance in the United Kingdom since September 2024. His last triumph at a ranking event occurred in January of that same year at the World Grand Prix.

The stakes extend far beyond rankings because O'Sullivan has made it clear that he will not play in the preliminary qualifiers if he drops out of the top 16. Instead, the 50-year-old has stated that retirement would be his preferred option over entering the grueling qualifying rounds at the English Institute of Sport in Sheffield. Other legendary figures, including Stephen Hendry and Mark Williams, have previously navigated the qualifying route after sliding down the rankings, but O'Sullivan intends to bypass that path entirely.

With his sights set on capturing a record-breaking eighth world title to eclipse Hendry before 2028, time is running short. While O'Sullivan has expressed a desire to keep competing for now, the mathematical reality of the rankings means his legendary career could face a definitive crossroads sooner rather than later.
