UFC Moscow Highlight Video: Karl Roberson Chokes Out Roman Kopylov

Karl Roberson had to overcome quite a bit of adversity to pick up a spectacular submission win over Roman Kopylov. Kopylov nailed Roberson with a nasty eye poke in the third round that caused a cut, and certainly affected Roberson's vision. However, Roberson was able to get the fight to the ground, take Kopylov's back, and lock in a deep rear-naked choke. Kopylov had no choice but to tap out.
