DUBAI - Virus-stricken Rory McIlroy, who dropped down the leaderboard Friday at the Dubai World Championship with bogeys at the 17th and 18th holes, says he cannot wait for the season to end.
"To be honest I'm ready for the season to be done," the 22-year-old said after a 71 left him five strokes behind leader Alvaro Quiros of Spain (64) after the second round of the European Tour's season-ending event.
"I am looking forward to putting the clubs away ... and taking a break."
Earlier Friday, a member of his management team told Reuters that McIlroy was "exhausted" and "run down" and was doubtful for next week's Asian Tour event in Thailand.
McIlroy has had a punishing playing schedule in Asia and says he is unsure of the nature of his virus, even though he has been under the weather for a couple of weeks.
"It could be Dengue fever, which is obviously carried by mosquitoes," he said after finishing with a seven-under aggregate of 137.
"It could have been food poisoning. It could have been a number of different things ... it could have been bacterial.
"I've just got lasting effects and my body is trying to fight it to get back to 100%."
McIlroy, who shrugged off his illness to lift the Hong Kong Open title last Sunday, is locked in a head-to-head tussle with Luke Donald for the right to end the season as top dog in Europe.
The Northern Irishman, who is second in the European money list, needs to win this week to have any chance of displacing Donald at the top.
Donald shot a four-under 68 on Friday to finish on 140, three behind McIlroy.
