Mark Allen's management stable, OnQ Promotions, have issued the following statement on his behalf:
"Following my recent comments in the press conference after my first round defeat to Cao Yupeng, I would like to formally apologise to anyone who may have been offended.
"Having taken some time to reflect on my comments I can appreciate that I over-stepped the line at a time when I was heavily influenced by the emotions of a disappointing defeat.
"I would like to take this opportunity to apologise to Cao Yupeng if he felt that my comments were insinuating he were a cheat. I stand by my opinion that the shot in question was a foul, but I also stand by my previous comments in the press conference that Cao was the better player and fully deserved to win. I genuinely wish him the best of luck for the rest of the tournament.
"I would also like to apologise to World Snooker. I appreciate the hard work by many people to grow our sport and I am truly horrified to think that my actions could be perceived to be detrimental to this.
"It is fair to say that this season has been one of ups and downs. The highs of winning my first ranking title and finishing runner-up in the UK championships have been overshadowed by some ill judged comments from myself.
"I realise that I need to ensure that my off table behaviour matches the standard and level of professionalism I set for my on table etiquette. I will return for the 2012-13 season with an improved approach to giving my opinions publicly."
