That is the second video I've seen showing a similar fate for a smaller yearling buffalo.

The first video I saw portraiting the same fate for the buffalo, had the buffalo running a bit faster, and the big bull actually lifted the smaller one into the air along with 3 or 4 wolves.

The wolves were then pulling the guts out of it as it landed. The big bull actually ripped open the younger one's belly with his right horn when it sent it airborn & cartwheeling.
