Boxing icon Floyd Mayweather Jr. isn’t ready to make nice with his estranged pal. The sports mogul went to social media this weekend to go off on G-Unit boss 50 Cent.

Last night, Mayweather Jr. delivered some digital KO punches on Fif about his rap career obstacles.

Initially, Fif went to Instagram Saturday to wave the white flag and low-key take one more dig at Floyd’s reading ability.

Earlier this summer, Fif went to Twitter to flame Mayweather about catching a huge on-court L.

A few hours prior, Fif went to Instagram to troll Mayweather over dropping big stacks on a massive Chanel bag.
