The two-time Crucible champion was booed into the arena ahead of his match with Liu Chuang, after calling the venue a "shithole" a day before the start of the tournament.

His twitter remarks were already described as "absolute lunacy" by snooker supremo Barry Hearn, and a fine is almost certain to follow.
But yesterday, the fans expressed their disgust as he walked out to play greeted with a chorus of boos, showing his reputation has taken a major battering.
Williams has enjoyed many great moments at the Crucible down the years but these appear to be count for very little among large sections of the crowd following his harsh comments.
It's actually no secret that the Welshman dislikes the venue. He's not been shy in saying before that he finds it too small. But it was the timing and lack of tact about his tweets that seem to have caused such a stir.
Snooker prides itself on the professionalism of its players and these twitter comments clearly broke that mould. While many people believe fury for Williams will subside, it's worth considering how rare it is for a player to receive such a frosty reception, and especially with such force.
I'm not so sure the Sheffield crowd will be quick to forget.
