Lost via TKO in round 1
HeavyweightUFC
February 20, 2021
Oleinik lost to Chris Daukaus via TKO (punches) at 1:55 of Round 1 at UFC Vegas 19 on Saturday.
ANALYSIS
Oleinik tried to get the fight to the ground urgently, but the fighter from Philly was wise to it and able to keep the fight standing. Daukaus' boxing ultimately proved to be too much for Oleinik. Oleinik is currently ranked in the heavyweight division, so it's worth monitoring his status once rankings are released next week. At this point, the 43-year-old should at least be thinking about booking a manageable fight to have a shot at pro win No. 60 before hanging up the gloves.

Oleinik will square off against Chris Daukaus on the Feb. 20 card, MMAJunkie.com reports.
ANALYSIS
Oleinix didn't make it far into the second round of his last bout versus Derrick Lewis before his night ended via TKO to break a two-fight winning streak. He's tasked with taking on a relatively new fighter to the UFC scene in Daukaus, who has earned first-round knockouts in each of his first two fights with the promotion. Oleinik incorporates more of the ground game than Daukaus despite holding a four-inch reach advantage over his opponent, so it will be interesting to see how he elects to attack his opponent.
Finished in second round
HeavyweightUFC
August 9, 2020
Oleinik lost to Derrick Lewis via TKO (punches) at 0:21 of Round 2 at UFC on ESPN+ 32 on Saturday in Las Vegas.
ANALYSIS
Oleinik was able to survive an early onslaught against Lewis in Round 1, even managing to get this fight to the ground -- where "The Boa Constrictor" typically thrives. There was likely around a 40-pound weight difference in this matchup, however, which was put on display in some of the grappling exchanges. Oleinik nonetheless managed to get Lewis in a side choke of sorts and was cranking hard, but Lewis didn't tap and eventually got out of it near the end of the round. Round 2 started with another Lewis blitz, as "The Black Beast" charged forward with a heavy knee, but it was the right hand that followed that put Oleinik on the ground. Lewis followed up with heavy ground-and-pound which forced referee Herb Dean to jump in and save a defenseless Oleinik. The story remains the same on Oleinik despite the defeat. He can submit any heavyweight on any given night, but the division's top talent can typically catch him on the feet.
Set for main event clash
HeavyweightUFC
August 3, 2020
Oleinik enters fight week as approximately a (+195) betting underdog for his heavyweight matchup against Derrick Lewis at UFC on ESPN+ 32 on Saturday in Las Vegas.
ANALYSIS
This matchup will serve as the night's main event, which would presumably help Oleinik due to Lewis' known cardio issues, though Oleinik has yet to get past Round 3 in the UFC himself. In fact, none of the 43-year-old's astounding 73 professional fights have seen the "championship rounds." The two men match up similarly from a physical standpoint, with Oleinik having a slight reach advantage and Lewis having a slight height advantage. Lewis has significantly more finishing power in his hands, which likely led to him being the favorite, but "The Boa Constrictor" will always have deadly grappling in his arsenal. The key for Oleinik will be to avoid the heavy shots early and get Lewis to the mat, which is certainly possible considering Lewis has just a 53 percent takedown defense. Both of Oleinik's 2019 losses in the UFC were via first-round knockout, however, so weathering the early storm is definitely easier said than done.
On track to fight Lewis on Aug. 8
HeavyweightUFC
June 16, 2020
Oleinik (undisclosed) is expected to take on Derrick Lewis in a heavyweight fight Aug. 8 at a yet-to-be-determined location in the United States, Damon Martin of MMAFighting.com reports.
ANALYSIS
The UFC plans to have the Oleinik-Lewis showdown serve as the headliner for the Aug. 8 card. Oleinik returns to the Octagon riding a two-fight winning streak, which includes a victory over Fabricio Werdum in his most recent bout. The 42-year-old's inclusion on the Aug. 8 card suggests he's on track to receive full medical clearance from the unspecified injury he suffered in the win over Werdum that resulted in him being hit with a 180-day medical suspension.

Oleinik was handed a 180-day medical suspension Monday, MMAJunkie.com reports.
ANALYSIS
The specific nature of Oleinik's injury was not disclosed, but he'll now be out until November unless cleared by a physician. He defeated Fabricio Werdum by split decision on Saturday but evidently took enough of a beating that he'll be sidelined for several months.
