Peter Wright was rushed to hospital with suspected gallstones on Thursday and is now a doubt for the PDC World Championship.
In a brief statement posted on Twitter, his wife Jo announced that the third-favourite for the world title is now back home but will not be taking part in exhibitions or competitions until he is well enough.
"I'm sorry to announce that Peter was rushed to hospital yesterday," Jo Wright posted from his official account.
"He is now back home but unable to do any exhibitions or work until he is well enough to. We would both like to apologise to all fans who have bought tickets to see Snakebite in the run-up to Christmas."
The Professional Darts Corporation later released a statement which clarified the problem and revealed Wright was back home.
"The world number two was rushed to hospital and diagnosed with suspected gallstones. He was released on Friday and returned to his Suffolk home, where the Scot is now recuperating," it read.
"Wright has withdrawn from his planned exhibition appearances in early December to recover from the illness."
The 47-year-old Livingston-born thrower is known for his flamboyant dress sense and colourful Mohican hairstyles and goes by the nickname Snakebite.
Wright defeated Phil Taylor to win the German Darts Masters in October - his first World Series of Darts title.
He then suffered a shock defeat in the first round at the Players Championship in Minehead at the end of last month.
Wright's management company MODUS confirmed the world number two would not take part in several events.
"Peter Wright will no longer be appearing (in) upcoming events at Lakeside, Bristol, Ipswich, Portsmouth and Brighton," the company said.
"World number two Wright was set to play in the exhibition events but has informed MODUS that he has been forced to withdraw through illness.
"Wright and MODUS apologise for any inconvenience caused. MODUS are looking to replace Wright with another top professional at next weekend's events."
The World Championships begin at Alexandra Palace on December 14 and number two seed Wright is slated to face Brazilian debutant Diogo Portela in the first round.
