Boxing legend Floyd Mayweather Jnr called Conor McGregor “Con Artist McLoser” after the Irishman’s loss at UFC 257, reigniting their feud. The 43-year-old Mayweather (50-0, 27 KOs) beat McGregor (22-4) via 10th-round TKO in a boxing crossover “superfight” in 2017. However, “Money” still has lingering hatred towards “Notorious” after previously claiming he made racist comments at press conferences leading up to their fight. McGregor, who was TKO’d in the second round by lightweight contender Dustin Poirier last weekend, denied any racially charged motive at the time. “I seen this post and my take on it is that the world knows Con Artist McLoser can steal everything from me and be loved but I’m hated,” Mayweather wrote in an Instagram post, responding to the supposed double standards in treatment despite both men carrying themselves in a similar way. “That just lets you all know that racism still exists. Just know, that bum will never beat me or be on my level. I’m just built different, my mindset it on another planet, my skills are second to none, I’m a natural born winner and yes, I talk a lot of trash, but every time I back it up! “This is what they hate. It’s so sad that you can be a poor black kid from the ghetto that has dealt with racism your whole life and work extremely hard to put yourself and your family in a better position, and most of the hate comes from my own people.” View this post on Instagram A post shared by Floyd Mayweather (@floydmayweather) Mayweather has remained largely inactive since retirement aside from an exhibition bout with Tenshin Nasukawa in 2018 . However, UFC president Dana White had long been teasing an upcoming project with Mayweather this year, which he has since put on hold because of the Covid-19 pandemic. Meanwhile, McGregor insisted he wants several more MMA fights this year. He also constantly mentions a potential bout with Filipino boxer and management labelmate Manny Pacquiao (62-7, 39 KOs). Both teams have confirmed ongoing talks. “Conor cannot even win in his own sport, but talking about coming back to boxing to fight Pacquiao. Nobody wants to see that, it’s like my leftovers eating leftovers,” Mayweather said.
