For most "major" professional Boxing and MMA fights, the weigh ins are the day before the fight. For low-level pro and amateur fights, the weigh ins may be closer to the fight.
This isn’t strictly boxing or MMA, but when I go to Judo tournaments, only the major tournaments (i.e. State or National championship tournaments) have weigh ins the day before. 90+% of tournaments have their weigh ins the day of the tournament.
The main reason for the time between the weigh ins and the fight is to allow the fighter to recover from cutting weight. Cutting weight takes a lot out of you, since a lot of the weight you are losing is by dehydrating yourself. If a fighter stepped into the ring or cage dehydrated, they would be putting themselves at unnecessary risk of injury.
They are not always 1 day before….
Day before the fight.
For example, the UFC’s last weigh in was 4pm pacific time friday. The main card was the following day, the main fights started at 7pm pacific time.
i think like the morning of the competition
1 day before
