Padraig Harrington has pulled out of the European Tour's flagship event at Wentworth this week.
The tournament is due to start on Thursday, but three-times Major-winner Harrington won't be there. The Irishman withdrew following a knee injury that first flared up at the US PGA Tour's Wells Fargo tournament earlier in the month.
He treid to play at The Players championship a week later but again was hit by the injury. He said: "The recommended course of action is a couple of weeks of rest. Reluctantly I am forced to withdraw from the PGA championship at Wentworth."
Harrington has not been playing well for some time now and has dropped to 43rd in the world rankings.
The news won't worry the Wentwprth organisers too much as they have a truly star-studded field with six of the world's top 10 players competing for the coveted prize.
The field also includes: Martin Kaymer, Lee Westwood, Luke Donald, Grame McDowell, Paul Casey, Rory McIlroy, Ian Poulter, Justin Rose, Darren Clarke, John Daly and Ernie Els.
