5 rarest submissions in the UFC

#2. Alexey Oleynik, Ezekiel choke

The only UFC fighter in history to win a fight using the Ezekiel choke, Alexey Oleynik is an unorthodox threat on the ground.

An exceptionally skilled grappler with 47 submission wins, Oleynik is also the owner of the most MMA victories with the Ezekiel choke, having used it to claim victory 14 times, with 2 of those wins coming in the UFC.

The last sighting of the submission came at UFC 224 when 'The Boa Constrictor' faced Júnior Albini.

In the 1st round, Oleynik secured what initially seemed like a standing triangle choke of sorts. Quickly pulling guard, the Russian kept his right arm hooked behind his foe's neck, grasping the bicep of his left arm as he slid his left hand under Albini's chin against the throat.

Wasting nary a second more, Oleynik tightened the squeeze by raising his arms until his opponent could no longer endure it and tapped out.

#1. Frank Mir, Toe Hold

When discussing the greatest grapplers in heavyweight MMA, it is difficult to discount Frank Mir's accomplishments.

Back in 2003, however, Mir was not yet the legend he is now revered as. Instead, he was a young MMA fighter taking part in his 4th UFC bout with the intention of extending his record to 5-1. Mir faced MMA pioneer Tank Abbott at UFC 41.

The future heavyweight champion needed less than a minute to secure a victory. The fight quickly hit the mat, enabling Mir to trap one of Abbott's arms with a figure-four leg-lock. With his foe's arm out of the equation, Frank Mir quickly hooked his arm around Abbott's ankle, while grabbing his wrist as his alternate hand seized his opponent's toes and twisted until the torque applied was too much for Abbott's ankle to bear.
