Louis Oosthuizen has not planned his 2014 schedule beyond the Masters in April as he manages a long-standing back problem.
The 2010 Open champion was forced to withdraw during a number of tournaments last year and was sidelined for almost three months until returning to action at the Presidents Cup in October.
The South African pulled out of the final round of the Byron Nelson Championship and withdrew from the US Open after a first-day 75 before lasting only six holes of the Open Championship at Muirfield.
But a series of injections allowed him to tee up for the International team at the Presidents Cup, and he managed to compete in each of the four Finals Series events on the European Tour.
Oosthuizen is in Durban this week to defend his Volvo Golf Champions title, and he plans to play eight tournaments in the next nine weeks despite his back issues.
"I had some injections in my lower back last October that seem to have helped," Oosthuizen said.
"The good thing is I am playing pain-free and I am doing a lot of things to get it better. But the pain is definitely still there and it's not going to go away, and it's going to take a lot of time.
"It's meant I've had to cut down my practice on the range, and while I'm taking the occasional antiinflammatory, it's just one of those things I have to deal with."
