UFC Stockholm had some great finishes. One of the most impressive was when Bojan Velickovic cracked Nico Musoke with a right hook. It was a counter right that landed flush that put Musoke on rollerskates. When the equilibrium takes a shot like that, the body just shuts down. Your brain is telling you that you are ok, but your body says no.
Velickovic followed up and the referee promptly stopped the fight. This fight specifically shows that no matter how good of a chin someone may have, if you get hit on the right spot, you are going down. That tko earned Bojan a nice little $50,000 bonus as well.
