Great fight, under the radar for obvious reasons. Bookies can't split them (basically even money the pair).
Both can bang and both been decked. Gvozdyk (17-0, 14 KOs) is the better boxer, Beterbiev (14-0, 14 KOs) is a Terminator. Gvozdyk has fought stronger opposition, however, Beterbiev has a stronger beard and a stoppage victory over Gvoz in the amateurs (TKO 2, bloody/busted nose).
Along with Prograis-Taylor this is the best divisional matchup of the year.
((How many here have even heard of them, let alone will watch? ))
