Defeats Mark Hunt via rear-naked choke in Round 1 in Moscow
September 15, 2018
Oleinik defeated Mark Hunt via submission (rear-naked choke) at 4:26 of Round 1 at UFC Moscow on Saturday.
It was almost certain that this fight would end with a Mark Hunt KO or an Aleksei Oleinik submission. It almost ended with a KO when Hunt landed a huge right hand early in the fight. He also landed multiple leg kicks that visibly affected Oleinik's ability to move. "The Boa Constrictor" was able to land a right hand that stunned Hunt and then he was able to secure a takedown. The single takedown was all that was needed as Oleinik easily took Hunt's back and sunk in a rear-naked choke which made Hunt quickly tap.
Pinned against Mark Hunt in Moscow
May 25, 2018
Oleinik will now take on Mark Hunt in a heavyweight battle at UFC Moscow on Sept. 15, Ariel Helwani of reports.
Oleinik had originally been pinned against Fabricio Werdum, but that fight was scrapped due to a potential anti-doping violation by Werdum. In steps "The Super Samoan," a fellow heavyweight over 40 that brings a 13-12-1 (1 NC) record into the Octagon. Hunt is known primarily for his striking, whereas Oleinik lives on his jiu-jitsu game, doing whatever it takes to bring the fight to the canvas. Hunt was once highly regarded for his takedown defense, but his stats will look a bit skewed due to the fact he was taken down 10 times by the younger, more athletic Curtis Blaydes in his last fight. It seems unlikely Oleinik gets a win via strikes here, as even at 44 years old, Hunt still has a good chin. For Oleinik to come out victorious, he'll have to find a way to drag the heavier Hunt to the ground, where he'll get a chance to work his submission game.
