Before Claressa Shields and Christina Hammer fight to crown the next undisputed champion in boxing, a pair of heavyweight bouts will take center stage on the televised undercard.
The April 13 Showtime-televised card from Atlantic City, New Jersey will open with undefeated heavyweight contender Otto Wallin taking on highly-decorated Nick Kisner. The fight will be Wallin's first in the United States and first since signing a promotional deal with Salita Promotions.
Wallin is currently ranked in the top five in both the WBA and IBF rankings at heavyweight and won the EBU European Union title in his last fight back in April 2018. Kisner sports a 21-4-1 pro record and is on a two-fight win streak. Kisner won the NABA-USA cruiserweight title in March 2018.
The co-main event bout is a heavyweight bout featuring undefeated heavyweight prospect Jermaine Franklin. Franklin will face former top-ranked amateur Rydell Booker in a 10-round fight. Franklin has won all 17 of his pro bouts with 13 of those wins coming from inside the distance. Booker, who once fought former world champion James Toney, was a rising heavyweight star in the early 2000s, but spent 12 years in prison and since being released, he has won three straight fights.
The main event fight will have Shields and Hammer fight for the undisputed WBA, WBO, WBC, IBF and Ring Magazine Female middleweight titles. The winner becomes the second active female boxer to hold all four major alphabet titles in a division, joining undisputed welterweight champion Cecilia Braekhus.
