The Masters snooker tournament has been moved from Alexandra Palace to Milton Keynes so strict Covid-19 regulations can be enforced.
Players at the tournament, which starts behind closed doors on Sunday, will stay in a bubble at the venue until they're knocked out.
The event has traditionally been held in the Alexandra Palace, London.
Our highest priority is always health and safety, and that is the basis of this decision," said World Snooker boss Barry Hearn.
"We staged several events in a strict bubble environment in Milton Keynes last summer and we were delighted that these were run successfully.”
"I trust the 16 players to accept this decision, follow the rules carefully and enjoy one of our greatest tournaments."
