The World Match Play Championship, held every year bar one since its inception in 1964, will not be staged this season.
"There will not be a World Match Play in 2010," European Tour chief executive George O'Grady told a news conference during the final round of the PGA Championship at Wentworth on Sunday.
"Plans are well advanced to bring it back on the schedule in 2011 but the dates are impossible to work out (this year) to the satisfaction of the promoter."
Wentworth hosted every World Match Play from 1964, the year Arnold Palmer beat Neil Coles 2 & 1 in the final, until 2007.
The tournament was not held in 2008 but returned last year at Casares in Spain where Briton Ross Fisher defeated American Anthony Kim 4 & 3 in the November final.
O'Grady also announced the tour had signed a new four-year deal with PGA Championship sponsors BMW.
Prize fund for the 2011 edition will be a minimum of 4.5 million euros ($5.63 million), the same as this year.
