UFC Vegas 25 poster released, featuring Dominick Reyes and Jiri Prochazka

The light heavyweight title picture could soon be shaken up.

Two-time championship challenger Dominick Reyes faces another stiff test on May 1 when he meets Czech sensation Jiri Prochazka in the UFC Vegas 25 main event.

The poster for their headlining matchup was released Tuesday.

Reyes (12-2) is coming off of the first two losses of his career, a close decision loss to then-champion Jon Jones at UFC 247 and a second-round TKO loss to Jan Blachowicz in a vacant light heavyweight title bout at UFC 253. Now he has to deal with the surging Prochazka, a former RIZIN champion who has won 11 straight fights.

In his UFC debut last July, Prochazka scored a second-round knockout of Volkan Oezdemir. He also holds recent KO/TKO victories over veterans C.B. Dollaway, Fabio Maldonado, Muhammed “King Mo” Lawal, and Brandon Halsey.
