Top Rank officially announced a big fight that had been expected for a while now, and it’s now set for Artur Beterbiev and Oleksandr Gvozdyk to unify a pair of light heavyweight titles on Oct. 18 in Philadelphia. Beterbiev (14-0, 14 KO) will defend his IBF 175-pound belt, and Gvozdyk (17-0, 14 KO) the WBC title. It’s not just a meeting of two highly-ranked, unbeaten titleholders, either — it’s also just plain a potentially fascinating fight stylistically.
