Ben Rothwell shocked Josh Barnett with the rare guillotine choke submission

Brutal.

Josh Barnett (34-8) looked to be well on his way to his fourth win in his last five appearances when the heavyweight slipped up for just a second against Ben Rothwell (36-9) Saturday night.

As Barnett tried to get a single-leg takedown, Rothwell slipped his hands over his opponent's head and clinched on a devastating choke that put him out for the night.

Rothwell has now rattled off four-consecutive wins, putting him in great standing for what could be a future shot at the belt.
