World number two Luke Donald has revealed that he will undergo an operation in the off-season in order to repair a problem with his sinuses.
The Brit admitted that the problem affected his game in the tour event in Dubai, but refused to blame his performance on the physical ailment.
"My sinuses are all completely clogged up and every time I get a little bit run down they turn into infections," the 34-year-old told reporters.
"Hopefully the surgery will fix it. It's a pretty quick and easy operation. I don't like to make excuses but the last couple of days I've had the sinus issue again. I felt a little bit flat and unfortunately I couldn't get things going on Sunday."
Donald, who finished third at the DP World Tour Championship event on Sunday, has seven European Tour victories to his name.
