(ROUGH CUT - NO REPORTER NARRATION)
STORY: An antelope tackled a mountain biker during a race in Albert Falls Dam, a nature park approximately 500 km (311 miles) southeast of Johannesburg.
Dramatic footage taken by cyclist Travis Walker who was riding behind Evan van der Spuy shows a large antelope crashing into the cyclist, knocking him down and the antelope running away.
Media reports say the cyclist was taken down by a Red Harteebest, a large antelope with a sloping back and a long narrow face. They are heavy, with adult bulls weighing an average of 150 kilograms (330 lbs).
These swift antelopes are known to be territorial, often presenting themselves prominently on mounds.
After the crash, van der Spuy could be heard groaning, getting up and looking at his shattered helmet.
Van der Spuy's message which he later posted on social networking sites said he was "stable with nothing more than a stiff neck."
