Karolina Kowalkiewicz, aged 38, is set to face 22-year-old Iasmin Lucindo in a UFC strawweight bout that highlights a significant age difference of 16 years. The fight will take place in Rio de Janeiro, Brazil, with Kowalkiewicz leveraging her extensive experience from 16 UFC fights, including a title challenge in 2016. Lucindo, on the other hand, offers a youthful dynamism to the Octagon. This matchup will expose the contrasting styles and stamina of experience versus youth in the UFC arena.

Simultaneously, UFC 301 will feature several key fights, including a flyweight title defense by Alexandre Pantoja against Steve Erceg.

Other notable fights include Anthony Smith versus Vitor Petrino and Michel Pereira against Ihor Potieria.
