This season, the top player in the world has already won the UK Championship and the Masters.
O’Sullivan, a vocal opponent of the snooker schedule, claims that the season has been difficult.
The 48-year-old posted on X, saying, “I hope to see you all soon and I’m sorry I won’t be there.”
“I adore the occasion and the German supporters, but my health and happiness must come first.
“It’s been a tiring and challenging season for me so far, despite how it may seem with the tournament wins so hope you understand.”
The seven-time world champion has won fifteen of the last sixteen games and has only lost three of the 33 thus far this season.
He won a thrilling World Open qualification in Barnsley on Wednesday, capping off his triumph in the World Grand Prix last week with a victory over Alfie Burden.
In the German Masters draw, Barry Pinches will replace O’Sullivan and face Julien Leclercq in the tournament that gets underway on Monday.
The 48-year-old posted on X, saying, “I hope to see you all soon and I’m sorry I won’t be there.” “I love the event and fans in Germany but I have to make my health and wellbeing the priority.”I hope you understand that despite how it may look with the tournament victories, this season has been demanding and exhausting for me thus far.”
