The Floyd Mayweather vs. Conor McGregor card will have free, televised prelims headline by former world champion Shawn Porter.
According to RingTV.com, Porter will fight former junior welterweight world title challenger Thomas Dulorme in the main event of a two-fight card on FOX right before the pay-per-view card starts.
Dulorme, who is signed to Mayweather Promotions, last competed in the untelevised undercard for the Badou Jack vs. James DeGale fight back in January. He defeated Brian Jones via sixth-round TKO in his only fight of 2017. Dulorme did compete for the then-vacant WBO junior welterweight title in 2015, being stopped in the sixth round by Crawford.
Porter currently is the WBC's mandatory challenger to Keith Thurman's welterweight title after beating Andre Berto earlier this year in a title eliminator. Thurman is out of action due to elbow surgery, but there were rumors that Porter would fight Danny Garcia in either a WBC title eliminator or a WBC interim welterweight title match. Porter even addressed the rumors by calling Garcia out while dressed as The Undertaker.
No word on what the second fight on that FOX card is, but the card will start at 7 p.m. The only other fight confirmed for the undercard is Gervonta Davis' upcoming IBF junior lightweight title defense. His opponent has yet to be announced, but sources told Fightful that Davis will most likely fight former world champion Rocky Martinez.
Showtime's Stephen Espinoza did say an announcement regarding the full undercard will be made official this week.
