what is a rehydration clause in boxing

A rehydration clause is a term in a boxing contract that sets a limit on how much weight a fighter can put back on between the weigh-in and the fight itself. It is often included in contracts to maintain a level playing field and prevent fighters from gaining an unfair advantage by ballooning up in weight after the weigh-in. The International Boxing Hall of Fame (IBHOF) looks after the WBC, WBA, WBO, and IBF matches and their moral grounds, and they insist that fighters cannot exceed a 10-pound rise. The rehydration clause helps to ensure a fair fight by preventing fighters from gaining too much weight and potentially putting their opponent in danger.
