It sure appears that the tracker got pownded. He is blotted out on purpose, it appears. If you stop the action as the buff charges you will see him flying toward the hunter and fall to the hunter's front left. It looks like the buffalo then pownds him as the hunter is shooting. In close inspection about midway through I can see the tracker's hand...near the ground in the middle of the blurred area.

It sure shows that buffalo hunting isn't a namby-pamby day's shooting afield!
