FLOYD MAYWEATHER NOT PAYING SUGE KNIGHT'S BAIL ... Says Money Team

EXCLUSIVE

Bad news for Suge Knight ... Floyd Mayweather will NOT be posting his $10 million bail if he wins his fight this weekend ... this according to a key member of Floyd's Money Team. 

TMZ Sports just got off the phone with one of Floyd's most trusted members of his TMT crew -- who tells us Suge's lawyer was just plain wrong when he told media outlets there was a plan in place for Floyd to fork over the money. 

We're told Floyd and Suge were close in the past -- but they haven't been in contact in several years. 

Suge is currently locked up in L.A. on murder charges -- and his attorney Matthew Fletcher reportedly said Knight was counting on Floyd to cover his bail.

We reached out to Fletcher for comment -- who says he only made the comments because that's what he was told by Suge's family.
