Mark Allen has withdrawn from the upcoming Champion of Champions tournament due to "personal reasons".
Defending champion Allen was due to compete at the tournament from November 15-21 at the Bolton Whites Hotel.
But the Antrim cue star has confirmed he will miss the event.
Allen tweeted: "Sorry to Matchroom and anyone who was for coming to watch me.
"Hopefully be back next year. One of my favourite events of the year. Hope the event is a massive success.
"Good luck to all involved."
Allen - who has struggled over the past couple of years with depression, divorce and financial difficulty - won last month's Northern Ireland Open in Belfast after beating John Higgins 9-8 in the final
The Antrim cue star, 35, later admitted he was "unsure if he would get any" of his £70,000 prize money for winning the event.
