WBC/IBF light heavyweight world champion – Artur Beterbiev’s October 23 title defense in Moscow against Adam Deines has been postponed after Beterbiev suffered a rib injury in training.

Beterbiev-Deines is expected to be rescheduled before the end of the year.

Beterbiev [15-0, 15 KOs], the only current world champion with a 100 percent knockout rate, has not fought since his 10th-round stoppage victory over Oleksandr Gvozdyk last October to unify world titles.
