Aleksei Oleinik (56-11-1 MMA, 5-2 UFC) is apparently set for a bout at the UFC’s debut in Moscow. Will Fabricio Werdum (23-8-1 MMA, 11-5 UFC) be his opponent?

This past week, UFC officials confirmed its Russian debut is slated for Sept. 15 at Olympic Stadium. Broadcast plans for the event, which is likely to be UFC Fight Night 136, haven’t been set.

And though no fights are yet official for the card, that could soon change.

On Sunday, Oleinik revealed a bout agreement for UFC Moscow, and an accompanying pen suggests he signed it (via <a href=" Oleinik, a 40-year-old Ukrainian-Russian submission specialist, recently scored a submission victory over Júnior Albini at UFC 224. After the victory, in which he scored just the second Ezekiel-choke win in UFC history (he also notched the first, against Viktor Pesta in 2017), Oleinik called for a fight with former champion Werdum, who’s No. 6 in the USA TODAY Sports/MMAjunkie MMA heavyweight rankings.

“People call him the best grappler in the heavyweight division,” Oleinik said. “It’s very interesting for me to try my grappling with him.”

Werdum is coming off a knockout loss to Alexander Volkov in March’s UFC Fight Night 127 headliner, and though UFC officials traditionally match up recent winners with recent winners, a fight with Oleinik is being discussed, according to MMA reporter Ariel Helwani (via Twitter):

UFC officials haven’t made a formal announcement, but Oleinik vs. Werdum would certainly be a marketable matchup in Russia.

Regardless, expect the card to start taking shape over the next few months.
