Padraig Harrington is one of five European Ryder Cup-winning players that will take part in the Nedbank Golf Challenge in South Africa during early December.
The three-time major winner is joined by Englishmen Lee Westwood and Ross Fisher as well as Italy's Edoardo Molinari and Spaniard Miguel Angel Jimenez in the invited 12-man field.
The tournament which is played annually at Sun City is celebrating its 30th anniversary in 2010.
Also amongst the participants will be three-time winner Ernie Els, along with fellow South Africans Tim Clark, Retief Goosen and Louis Oosthuizen, who won the The Open at St Andrews earlier this year.
Last year's winner Robert Allenby from Australia will also be playing at the Gary Player Country Club, while England's Justin Rose and Dane Anders Hansen complete the line-up.
Tournament director Alastair Roper said: "We can never hope to make accurate predictions, but judging by the form shown by our invitees this year it is fair to assume that we can look forward to a thrilling contest."
