on fight night against Hatton? On a related note, does anyone have a link to fight night weights or a list you've compiled?
No it wouldn't. Mayweather doesn't cut a lot of weight to make the weight class. Mayweather on fight night weighs 146-149.
I don't believe they revealed the fight night weights for that fight. However, Mayweather was between 147 and 149 for all his other WW fights on fight night.
Someone had it from the UK. We were discussing it quite awhile back and someone provided the info with a link.
When floyd faught zab he weighed in at 146 and on fight night was still 146 if that tells you anything
