Two years ago, Derrick Lewis agreed to a title fight just one month removed from a grueling battle in the Octagon. Although the circumstances were less than ideal, the fourth-ranked heavyweight couldn't pass on the opportunity to earn a UFC belt. His quest towards another opportunity continues on Saturday when he faces Aleksei Oleinik in the main event of UFC Fight Night: Lewis vs. Oleinik. The meeting of top-10 heavyweights tops the Lewis vs. Oleinik fight card at the Apex facility in Las Vegas, with the main UFC card set for 9 p.m. ET.

Lewis battled former champ Daniel Cormier in November 2018 and came up short amid nearly impossible circumstances, but he's now on track for another shot with two straight wins. In order to make it three, he will have to get past the No. 10-rated Oleinik, who has won four of his past six. Lewis is a -200 favorite (risk $200 to win $100), while Oleinik is +170 in the latest UFC Fight Night: Lewis vs. Oleinik odds from William Hill. In the co-main event, former middleweight champion Chris Weidman (-120) takes on surging prospect Omari Akhmedov (+100).

Derrick Lewis vs. Aleksei Oleinik expert preview

Wise knows the 35-year-old Lewis is popular with UFC fans because of his finishing ability and unfiltered interviews that often garner more attention than his fights. However, the Texan's stamina and ability to take damage have been question marks throughout his career.

Lewis has vowed to improve his conditioning, and the results can be seen with three of his last four victories going the distance. The outlier in that span was a knockout of Alexander Volkov at 4:49 of the third round.

His stamina likely will be tested by the savvy Oleinik, who will be looking to avoid power shots while trying to get the fight in his comfort zone on the mat.

The 43-year-old Russian has remained viable because of the relatively low level of damage he has taken throughout his career and his uncanny ability to end fights the moment he gets hold of a limb. The Brazilian Jiu-Jitsu black belt has won numerous grappling tournaments and also has five Performance of the Night bonuses in the UFC to his credit.

Top UFC Fight Night predictions

We'll share one of Wise's UFC Fight Night main-card selections here: He is backing Beneil Dariush (-160) to get a stoppage victory against Scott Holtzman (+140) in a matchup of lightweight contenders. 

The affable and versatile Dariush (18-4-1) is arguably one of the hottest fighters on the UFC roster. The 31-year-old Californian bounced back from a first-round knockout loss with four consecutive victories against upper-tier opponents. His streak includes stoppage wins over fellow prospects Drew Dober and Drakkar Close, whom he finished in the second round of their March battle.

Holtzman (14-3), 36, is 5-1 in his last six appearances in a stretch that dates to April 2017. The Tennessee native is a former lightweight champion in the Xtreme Fighting Championships promotion, where he went 6-0 in a 20-month span. 

"Dariush is the more well-rounded fighter. Holtzmann has never been finished in his career but Dariush has the power to get the job done," Wise told SportsLine.
