Roy Jones Jr.-Anderson Silva Unlikely for Floyd Mayweather-Conor McGregor Card

While the highly anticipated matchup between Floyd Mayweather Jr. and Conor McGregor has come to fruition, it won't necessarily be the start of more cross-sport battles.      

According to TMZ, UFC President Dana White said the undercard of the Aug. 26 bout in Las Vegas would not likely feature Roy Jones Jr. vs. Anderson Silva.

Mayweather confirmed the date of the fight against UFC star McGregor on his Twitter account Wednesday.

Although this potential bout remains a possibility with both fighters interested, White noted the boxing undercard will be handled by Mayweather Promotions.
