The Daily Mail reports that Ronnie O'Sullivan has told World Snooker he is withdrawing from the Betfred.com World Championship.
However, O'Sullivan has apparently had a rethink and is consulting with a leading sports psychologist ahead of the Crucible.
According to the newspaper, O'Sullivan said: "Last week I put in a verbal withdrawal to World Snooker and told them I wasn't going to play in Sheffield. That's when it really hit me that this could be it, for five or 10 minutes my heart was pounding.
"I said if it's easier to say I'm retiring then say that. They said that's fine, but we'll give you the weekend to think about it. On Monday they called back, and talked me back into it."
O'Sullivan, who won the world title in 2001, 2004 and 2008, is due to play Dominic Dale in the first round.
He has been largely de-motivated this season, has fallen to tenth in the world rankings and has not won a match in a ranking event since last September's World Open.
The Mail reports that O'Sullivan is consulting with Dr Steve Peters, who advised the British cycling team ahead of the 2008 Beijing Olympics.
