Following the final press conference, Terri Harper and Natalie Zimmermann successfully weighed in for their 135-pound championship bout. The pair square off in the main event at Eco-Power Stadium in Doncaster, England on May 23.
Local three-weight champion Harper (15-2-2, 6 KOs) came in at 134.7 lbs for the first defense of her WBO belt. Unbeaten challenger Zimmermann (13-0, 3 KOs) of Germany was 134.12 lbs for her first attempt to become champion.
Maxi Hughes (28-7-2, 6 KOs) and Archie Sharp (25-1, 9 KOs) tipped the scales at 134.6 lbs and 134.8 lbs, respectively. The contest serves as the co-main event. The pair battle it out for the WBC “Silver” strap.
Reece Mould (20-3, 6 KOs) and Lewis Sylvester (15-1, 4 KOs) both showed 134 lbs for their clash, with the vacant IBO Continental belt on the line.
