5 rarest submissions in the UFC

#4. Chan Sung Jung and Bryce Mitchell, Twister

Only two fighters in UFC history have managed to finish a fight with a twister. Curiously, both fighters are featherweight contenders.

The first was two-time title challenger Chan Sung Jung in his UFC debut when he defeated Leonard Garcia in the very last second of the 2nd round at 4 minutes and 59 seconds. Meanwhile, the undefeated Bryce Mitchell secured a twister in his 3rd UFC fight against Matt Sayles in the 1st round.

The submission in question involves hooking one's legs over one of the opponent's legs to hold it in place. Meanwhile, the opponent's arm is pinned under the back of one's neck or upper-back while wrapping one's arms around the opponent's face and cranking their head towards the side opposite of the one the opponent's trapped leg is facing, thereby twisting the spine to an excruciating degree.

#3. Former UFC lightweight champion Charles Oliveira and Brett Johns, Calf Slicer

Long before the legendary 11-fight win streak that most recently saw former UFC lightweight champion Charles Oliveira defeat Justin Gaethje, the Brazilian was a weight class below.

Making his featherweight debut, Oliveira was booked to lock horns with Eric Wisely. It did not take 'Do Bronx' long to reveal the depth of his Brazilian jiu-jitsu skills, as within a minute of the 1st round, Oliveira trapped Wisely in a compromising position.

After trying to escape the kneebar, Wisely exposed his back, allowing Oliveira to secure a rear-bodylock before triangling one of Wisely's legs. Keeping his leg behind his foe's knee, the Brazilian pulled him back, applying immense pressure to Wisely's calf until it was pressed against the bone.

Brett Johns, a formerly undefeated bantamweight, used the same submission against former bantamweight title challenger Joe Soto.
