As Terence Crawford and Julius Indongo fought for all the major belts this past weekend (WBA, WBC, WBO and IBF), neither fighter was required by the IBF to participate in a second weigh-in before the fight. Their rules state that boxers who are in IBF title fights can not weigh more than 10 pounds above the weight limit.

IBF president, Daryl Peoples, while on vacation sent a statement, via text, to BoxingScene.com:

"During the IBF convention in May, we decided to waive the second day weigh-ins for unification bouts. However we encourage all fighters to participate in both weight-ins," Peoples stated.

This rule change probably stemmed from the situation that took place on March 18th when unified middleweight champion Gennady Golovkin faced Daniel Jacobs in New York.

Golovkin, who has the WBC, IBO, WBA and IBF titles, was obligated to participate in the Saturday morning weigh-in if he wanted to fight for the IBF belt.

Jacobs, perhaps gaming the system, decided not to go through with the IBF procedure and made the decision to just compete for the WBC and WBA belts. Many believe that Jacobs came in significantly heavier than Golovkin as they both stepped into the ring at Madison Square Garden.

Perhaps sensing that this rule would unfairly handicap unified belt-holders like Golovkin, the IBF made this amendment.

On September 16th Golovkin faces Saul 'Canelo' Alvarez as he puts his middleweight titles on the line.
