Video: Watch Dennis Siver's vaunted spinning back kick crush a man's ribs

While Conor McGregor (16-2 MMA, 4-0 UFC) seems to think Dennis Siver (22-9 MMA, 11-6 UFC) is little more than a stepping stone on his path to the UFC’s featherweight title, the Russian-born striker has ended some opponents’ nights in painful fashion.

McGregor and Siver meet in the headlining bout of next week’s UFC Fight Night 59 event. Oddsmakers have McGregor set as high as 12-to-1 in the role of favorite, but Siver isn’t out to play anyone’s punching bag.

To see what Siver is capable of doing in a flash, watch his UFC 105 matchup with Paul Kelly (14-5 MMA, 5-4 UFC), where one brutal technique earned Siver a win.
