Former Race to Dubai champion Henrik Stenson acknowledges that the remainder of his 2015 campaign might be hampered by a right knee injury.
Stenson, who is also trying to maintain a card on the United States PGA Tour, has a busy schedule ahead of him in coming weeks.
For Stenson, there is also the added complication of an Olympic Games campaign, set to take place in Rio next year.
The general plan appears to be that the Swede is trying to get as many tournaments as possible under his belt ahead of the Christmas break.
"I'm playing five out of six weeks and the only little slight worry is my right knee," said Stenson ahead of the CIMB Classic.
The European Tour Finals Series starts in Turkey this week but Stenson has prioritised the US PGA instead.
"I've got a bit of a problem with the meniscus and I'm scheduled to have an operation on the 9th of December in Orlando, so I'm hoping I can squeeze by in these last five tournaments that I have before Christmas," added Stenson.
"Part of the reason that I've added this tournament to my schedule is because next year is going to be a busy year with the Olympics and Ryder Cup and everything else," said the former FedEx Cup champion.
"This gives me the opportunity to add one more tournament before Christmas. I will have this one and the WGC-HSBC Champions next week, so I will have two PGA Tour events played before Christmas, which is going to ease off my schedule."
