Peter Dawson, president of the International Golf Federation, released the following statement: "The IGF understands the challenges players face in terms of scheduling this summer and it is regrettable to see a few leading players withdraw from this year's Games. The Olympics is the world's greatest celebration of sport and it is exciting and appropriate that golf features in its programme again. Real history will be made at this year's Olympic competitions and it is our belief that the unique experience of competing will live forever with athletes that take part."
Another top player has decided to pass on the Olympics.
“I have always represented South Africa with pride so I didn’t make my decision without a great deal of thought,” he said in a statement released through his management company.
