T-Mobile Arena in Las Vegas will host UFC 303 on Saturday night. The headliner was supposed to feature Conor McGregor, the one-time UFC Lightweight and Featherweight Champion, along with Michael Chandler, the former three-time Bellator Lightweight World Champion. An injury to McGregor forced the postponement of that main event, but the top of the card will still bring plenty of intrigue as Alex Pereira will defend his UFC Light Heavyweight belt against former champion Jiri Prochazka.
