Michal Oleksiejczuk will attempt to extend his unbeaten streak to 13 fights when he meets Octagon veteran Ovince Saint Preux at UFC Copenhagen on Sept. 28, the promotion announced.
Oleksiejczuk (14-2, 1 no-contest), who had his first UFC win over Khaili Rountree overturned after testing positive for clomiphene in 2017, made quick work of light heavyweights Gian Villante and Gadzhimurad Antigulov earlier this year, stopping both fighters in a combined time of 2:18.
Saint Preux (23-13) has his back against the wall after losing three of his last four UFC appearances to Ilir Latifi, Dominick Reyes and Nikita Krylov.
