According to Top Rank's CEO Bob Arum, junior welterweight contender Mike Alvarado (33-1, 23KOs) will likely contend for the vacant WBO championship in his next fight.

The vacant belt would provide Alvarado with the opportunity to fight for a belt - and Ruslan Provodnikov (22-1, 15KOs) is a potential opponent.

"The WBO title will be vacant because Marquez is giving up the title, the 140-pound title, and I think [WBO President] Paco [Valcarcel] would sanction Ruslan Provodnikov with Alvarado - and that would be one hell of a fight," Arum said.
