One minute, Evan van der Spuy was competing in a South Africa mountain bike race; the next, he was flat on his back after a charging antelope rocked his world. The Red Hartebeest buck slammed right into the 17-year-old, then got to its feet and ran off, the Telegraph reports. It appeared unhurt, but van der Spuy was taken to the hospital with a minor concussion and whiplash; his helmet shattered. Fellow biker Travis Walker caught the whole thing on tape. The Telegraph notes that the Red Hartebeest generally has miserable vision. (More viral video stories.)
