UFC president Dana White announced on Friday the official lineups for UFC Fight Night events on May 13 and May 16 in Jacksonville, Florida.

The two cards are part of the UFC's effort to resume normal operations in the wake of the coronavirus pandemic shutting down much of the sports world. The plan includes three live events in an eight-day span, beginning with UFC 249 on May 9.

A light heavyweight matchup between former title challengers Anthony Smith (33-14) and Glover Teixeira (30-7) will headline UFC Fight Night on May 13. A heavyweight bout featuring another former title challenger in Alistair Overeem (45-18) and Walt Harris (13-7) will headline the UFC Fight Night on May 16.

Both headliners were originally scheduled for different dates and locations, before the postponements due to COVID-19. Smith was supposed to face Teixeira on April 25 in Smith's home state of Nebraska, while Overeem and Harris were slated to headline an event on April 11 in Portland, Oregon.

White said last month that all three events in May will take place without a live audience.

The UFC has been forced to postpone a total of six events, but it has been adamant it will be the first major sports organization to return -- and still hold its entire 42-event schedule in 2020. The UFC is the only MMA organization with concrete plans to hold an event in the near future. Bellator MMA has postponed its schedule through June, and the Professional Fighters League, a tournament-based promotion, suspended its entire 2020 season.

An interim lightweight title fight between Tony Ferguson (25-3) and Justin Gaethje (21-2) will headline UFC 249 on May 9. That event is a pay-per-view, and will air on ESPN+.
