Shaun Murphy has expressed his disappointment with Ronnie O'Sullivan and Judd Trump for not attending the official media day before the World Snooker Championship, stating that their absence may harm the sport's promotion. O'Sullivan and Trump, who are set to compete in the tournament, may face penalties from the governing body for missing the traditional pre-tournament event. Murphy commented, 'It's a shame they didn't turn up, as they could have done more to promote the game over the years.' The top seeds are scheduled to start their tournament on Tuesday, with O'Sullivan and Trump facing He Guoqiang and Gary Wilson, respectively. Meanwhile, Zhao Xintong will begin his title defense against Liam Highfield, and Mark Allen will face Zhang Anda in his quest for his first world crown.
