Ronnie O'Sullivan is set to compete at the World Seniors Snooker Championship at the Crucible in May.
The 50-year-old, who is still ranked as high as 11th in the world and is still active on the main professional tour, has signed up for the competition that takes place a week after the World Snooker Championship at the same venue.
The senior event, which runs from 6 to 10 May in Sheffield, will also feature debutant and 2015 world champion Stuart Bingham, 12-time women's world champion Reanne Evans and former Masters and UK champion Matthew Stevens.
World Seniors Snooker Tour chairman Jason Francis said of O'Sullivan's maiden involvement: "The most commercially valuable player the sport has ever seen will make his seniors debut at the Crucible in May in an attempt to add another world title to his CV - wow!
"We've already sold more tickets than we did for the entire event last year, and Ronnie's participation is set to drive even greater demand."
O'Sullivan relocated to Dubai last year but will spend April and May in Sheffield as he also attempts to win an eighth world title when he appears in his 34th consecutive World Snooker Championship.
Changes to the seniors tournaments rules have meant players ranked in the world top 64 are eligible to take part with several having taken the opportunity.
With four title wins the most successful player in the seniors is Jimmy White, with the 10-time ranking event winner also slated to take part.
Ireland's Ken Doherty, Tony Drago, Anthony Hamilton and current Seniors British Open Champion Joe Perry are also set to be in the draw.
