Two-weight world champion Jonas makes the first defence of the IBF belt she captured last year, having previously earned the Ring championship at junior middleweight as she unified the WBC, WBO and IBF belts. Mayer, a former inaugural Ring junior lightweight champ, looks to reclaim world honours as she moves up to challenge for Jonas’ welterweight crown.
