You were wrong about that (half of your post). And you were wrong about Floyd using Lidocaine while Pac doesn't (the other half of your post).
Absolute BS Pacquaio did NOT receive Lidocaine before the May 2 fight. The NSAC even confiscated his water & vitamins too. Mayweather was allowed to use Xylocaine as usual & that really is Lidocaine anyway Plus Mayweather was allowed the illegal IV too with NSAC's blessing C'mon people youre not that naïve are you??????
using an approved medication to heal an illness for the fight to happen is different from intently using a drug for performance enhancement while perfectly healthy and or capable to fight by the sports rules. a lot of rules were just technically set aside just to make a lot of money.
