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.
