According to TMZ Sports in early July 2017, it was reported that Gervonta Davis would feature in the co-main event of Floyd Mayweather Jr. vs. Conor McGregor on August 26, 2017 at the T-Mobile Arena in Paradise, Nevada. On July 29, The Ring Magazine reported that Davis would likely defend his IBF title against former WBO champion Martínez. On August 10, Ringtv reported that Davis would instead fight unbeaten prospect Francisco Fonseca (19-0-1, 13 KOs), who at the time was ranked number 7 by the IBF. According to some sources, the potential fight with Martínez was dropped due to notice and Martínez would not have had enough time to make the 130 pound limit.
