American pro Dustin Johnson is likely to spend two months away from the course while recovering from knee surgery.
The 27-year-old underwent arthroscopic surgery yesterday, in order to cure a long-term pain in his right knee.
"All is well - no worries! Feelin' good...or is that the meds!? Appreciate all the support but it's all pretty minor stuff," Johnson posted on Twitter.
Johnson's doctor stated: "His prognosis is excellent and we expect a quick and speedy recovery."
The five-time PGA Tour winner is expected to return to practice towards the end of December.
