Henrik Stenson is hoping that his illness will not effect his golf as he heads to the Volvo China Open.
The European Tour event starts on Thursday and Stenson is the favourite to be victorious at the Shenzhen Genzon Golf Club.
However, the Swede has admitted that he has recently been struggling to overcome an illness and he hopes that it will not be a hindrance on his play.
He told Sky Sports: "I am just kind of waking up to be honest after a little bit of flu.
"I am still a bit weak after spending the last 36 hours in bed, but I am slowly getting there and hopefully I can rest up and drink lots of fluids and be a bit better tomorrow (Thursday) and be ready to play."
The 38-year-old enjoyed a successful 2013 season, which culminated with a win at the final European Tour event of the year, the DP World Tour Championships, in Dubai, but he has struggled to find his feet on the tour this campaign.
Stenson has finished in the top ten just once at an event this season, back in December of last year, at the Nedbank Golf Challenge, and he says that it has been hard to maintain focus after his excellent spell last year.
"There has been a little hangover from last year after so much success and then all the resulting commitments that come off the course," he said. "I have only really had a two-week break from it all and it has been tough to kick-start a new season when you are quite low on energy. But other than that I am right on track.
"I didn't have a great start to the season last year so I am in the same position as I was going into the summer. I played pretty well at the Masters without nailing it, but I am happy with the game.
"I didn't plan on having a virus for the 20th Volvo China Open, but I am here and will do the best I can."
Stenson’s illness has already forced him to withdraw from the pro-am, which takes on the Wednesday prior to the tournament start-date, but he did indeed play well at the Masters last fortnight – where he finished in tied 14th position – and he will need to emulate this sort of performance if he is to hope to come out on top in China.
The field at the event is a strong one and some of his major competition may come from the likes of Ian Poulter and Nicolas Colsaerts.
Guan Tianlang, who made history by becoming the youngest player to ever make the cut in the Masters last year, at the age of 14, will also want to show that his game has developed and matured in recent times and he is also in the line-up in China.
