The IBF has confirmed that a final eliminator between Errol Spence Jr (20-0, 17 KOs) and Konstantin Ponomarev (30-0, 13 KOs) will be heading to purse bid next week as the two sides have yet to hash out a deal between themselves. The purse bid will be held on May 17th for a fight that will determine the next mandatory challenger or IBF titlist Kell Brook (36-0, 25 KOs).

But since Brook just fulfilled his mandatory defense this past March, when he stopped Kevin Bizier in two rounds, he won't be required to negotiate with the winner of Spence-Ponomarev until at least the end of the year. That paves some room for Spence and Ponomarev to take care of their business, but the two are expected to face one another this summer.

Spence, a highly touted prospect who is now likely considered a legitimate title contender, will be favored in the match-up against Ponomarev - and should he win, a fight against Kell Brook should be a tough test for both men.

So, just for the sake of prognosticating, who would you favor in a title fight between Brook and Spence? How do you see that fight playing out? Sound off in the comments below.
