Tough fight to call. If Masternak can effectively keep Czakiev off him, and keep him from rushing in, I think he can outpoint him. But whether he can do that or not is another story.
Seems as though the fight will not be happening, according to the last article I read on ringpolska which quoted Master that he got a letter from EBU that unibrow relinquished his rights to be a pretender for that title.
