The Floyd Mayweather boxing comeback is back on -- he's actively looking for new exhibition fights after shutting things down earlier this year.
We broke the story ... Mayweather had previously been gunning for 2 fights in 2020 -- one against a pro boxer and one against an MMA star (he was really into the idea of Khabib Nurmagomdov).
But some unforeseen circumstances changed those plans -- not just the COVID pandemic ... but Floyd was also crushed by the unexpected deaths of his uncle Roger Mayweather and Josie Harris, the mother of his children.
