Boxing icon Floyd Mayweather Jr. is low-key about that octagon life. The sports mogul has flexed his love for MMA and even named who he believes is the best in the sport.

Floyd went to Instagram Sunday to co-sign fighter Makhmud “Mach” Muradov.

Recently, Mach jumped on IG to salute Mayweather for supporting and believing in him.

Over the past few days, Floyd has engaged in a savage e-beef with one-time boxing rival and UFC star Conor McGregor.
