Natasha Jonas and Mikaela Mayer make weight ahead of Saturday’s welterweight title clash

IBF welterweight world champion Natasha Jonas (14-2-1, 9KOs) and American adversary Mikaela Mayer (19-1, 5KOs) both made the 147-pound weight limit ahead of their fight at the M&S Bank Arena, Liverpool.

Jonas is making the first defence of her title, which she collected by defeating Kandi Wyatt in July of last year in eight rounds, becoming a two-weight world champion. 

Jonas, a former GB olympian at the London 2012 Olympics, previously held three of four world championship belts at super-welterweight, defeating then champions Chris Namus, Patricia Berghult, and Marie Eve Dicaire in consecutive fights and relieving them of their belts.

Mayer is hoping to defeat Jonas and become a two-weight world champion herself following a successful period as unified WBO and IBF world super-featherweight champion, eventually dropping to a narrow and controversial defeat Alycia Baumgardner in 2022 in an undisputed title affair at London’s 02 Arena. 

Mayer has since rebuilt her momentum following the defeat to her compatriot with wins against Lucy Wildheart and Silvia Bortot, with both wins coming by comfortable unanimous decision verdicts.

Challenger Mayer first stepped on the scales and weighed 146.3lbs. Jonas followed to a warm welcome of applause and would officially weighed 146lbs even.

Jack Cullen and Zak Chelli will face each other again on the Jonas-Mayer show, three and a half years after their original split decision draw in August of 2020 at Matchroom Boxing HQ in Brentwood, Essex.

Cullen makes the first defences of his British and Commonwealth super-middleweight titles, which he collected in defeating Mark Heffron in September of last year inside three rounds.

Chelli, a talented fighter yet to fully fulfill his potential, will be hoping to claim the first major domestic titles of his career. Chelli weighed 166.3 lbs, and champion Cullen tipped the scales at 167.3 lbs.
