According to Dan Rafael of espn.com, the IBF will abolish 2nd day weigh ins in unifications bouts.
“Second-day weigh-ins will remain in effect for all other [IBF] bouts,” IBF president Daryl Peoples told ESPN. “We changed the second-day weigh-in for unifications after we received a request from one of our members. We had discussed changing the rule prior to the request.
“Naturally, we would like to see both fighters participate in the second-day weigh-in for safety reasons. However, we found that some fighters were not participating in the second-day weigh-ins, and those fighters that complied with the rule had a disadvantage due to weight disparities on fight day.”
