Canelo/Kovalev has a 180 lbs rehydration clause

[TRTboy]

If its in the morning of the fight it wouldnt matter, he will still be gaining weight until the fight, another rise of 5 to 10 water weight is no problems by fight time.

Yes it does matter a lot. Lol it means after the weigh in Kovalev cant drink or eat much for the entire night.

That's ****ed up. That's when fighters usually eat, drink and recover and get a good sleep.

That's such a ***** stipulation imo
