Floyd Mayweather ain't ready to close the book on a possible Conor McGregor fight -- saying it's still up in the air ... and hinting that he'll do it if the money is right.
With McGregor once again hinting at a match with Floyd during the UFC 205 media event on Tuesday, we had to ask Floyd how he felt about it.
Long story short ... Floyd says it's super difficult to put the fight together -- as we all know from the first time he tried to make it happen -- but wouldn't say it's completely off the table.
"Are we going to fight? I just don't know."
Mayweather also praised Conor as a great fighter who's "very good" at stand-up fighting.
One last thing ... we asked Floyd if he was planning to stay retired -- and his response, "For a couple bucks, you just don't know."
