The WBO cruiserweight championship has been declared vacant as part of a months-long legal battle arising from Maris Briedis' foul-tainted victory over Krzysztof Glowacki last June. That fight was part of the World Boxing Super Series. Briedis landed a deliberate foul, an elbow to the jaw of Glowacki, that hurt him badly but went unpunished by referee Robert Byrd. A few seconds after Glowacki got up from the foul, Byrd allowed the boxers to continue fighting well after the bell sounded to end round two, leading to Glowacki suffering a hard knockdown about ten seconds after the bell rang. Again, Byrd did nothing. Briedis admitted in his post fight interview that the elbow was deliberate and that he heard the bell but kept fighting anyway. Glowacki protested to the WBO, and after an arbitration was held in Puerto Rico, the WBO ordered Briedis to give Glowacki an immediate rematch. Briedis refused, intending to fight IBF champion Yuniel Dorticos in the finals of the World Boxing Super Series, although that fight still has not been scheduled. Glowacki will now await the WBO to name the co-challenger for the vacant title. NOTE: Glowacki was represented in the arbitration by Scott Shaffer, the author of this article.
