Ronnie O'Sullivan has suffered an injury scare just four weeks before the World Snooker Championship is due to get underway.
O'Sullivan pulled out of the inaugural WST Classic with an injury ahead of a second round match against David Grace. Grace has now been given a bye to the last 32, where he will take on Jamie Jones.
O'Sullivan earlier beat Mohamed Ibrahim 4-2 in the first round of the tournament, hitting two century breaks in the process. "Ronnie O'Sullivan has withdrawn from the WST Classic in Leicester for medical reasons," a statement from the World Snooker Tour read.
