This video has been widely circulated.  You can see the rider at the end of the video; he appears to be OK, he was just dazed.

He’s lucky he wasn’t killed.  You can see the rider knew the antelope was rushing him [he waved his hand at it].  The antelope sighted the rider and decided he was a threat.   It’s odd.  The rider could see the beast rushing him but didn’t seem to think he was on its trajectory.  Then Blammo!  I’ve had to smack dogs on their muzzles with my frame pump but shit! how do ya fend off a charging antelope.  How much do antelopes weigh?   The eland is the largest of Africa’s antelopes.  They can be as tall as 178 cm [5' 9"] at the shoulder, and a big one can reach 950 kg [about 2090 pounds.  Damn! That's lots'o animaux rushing you].  The one in the video looks impressively big [Animaux].

No one carries frame pumps anymore. We’z all so impatient now.  Better ditch the ride when you see the Animaux rushing at you.
