Arum & Koncz have slammed Mayweather's statement, although haven't gone as far as to deny it.

Team Pacquiao, Arum Slam Mayweather's 14-day Story - Boxing News

The choice quotes:

Arum

"after the horses leave the barn and they rejected Manny's 24 days offer he now comes up with 14 days which is totally unacceptable"

"this is not a swap thing among a bunch of kids"

"we agreed to go to 24 days before the fight for a blood test but he rejected it and that's it. It's over"

Most interestingly Arum feels that because 'the fans' are blaming Mayweather for the collapse of the fight, he's trying to turn it around, but it's not working

Koncz

sees PBF's statement as "both humorous and ludicrous all in one"

has been told my drug experts that PEDs "will be in your blood for 40 days before the fight or the day after the fight. Whatever is there is there for that period. So what the hell does 14 days have to do with it? Nothing other than to irritate Manny, knowing that he has whatever, a fear or superstition of extracting blood less than 30 days"

Sorry, had to highlight that last bit

His superstition only kicks in 30 days before a fight

Seriously, every time I think that there's nothing Arum & Team Pacquiao can do to make themselves look more stupid, there they go and confound expectations again
