Artur Beterbiev vs. Karo Murat planned after Sullivan Barrera runs into visa troubles

The proposed IBF eliminator between Artur Beterbiev and Sullivan Barrera, planned as a co-feature with the WBC eliminator between Eleider Alvarez and Isaac Chilemba, has hit a snag.

Barrera will reportedly be unable to secure a visa in time, removing him from consideration. The fight with Beterbiev was then offered to Yunieski Gonzalez, who in the eyes of many got a raw deal against Jean Pascal, but the Cuban turned down the offer. As a result, talks are in place to pit former Hopkins foe Karo Murat against the Russian knockout artist.

Murat (27-2-1, 17 KO) has fought once a year since a 2011 draw with Gabriel Campillo that he might not have deserved. In 2013, he managed to drag an entertaining fight out of Bernard Hopkins, which is no mean feat, btu ultimately came up short in his bid for "The Executioner's" IBF title.

He's scored two knockouts since, picking up the IBF International title in the process.

I suppose Murat isn't the worst option, considering that Hopkins, Erik Skoglund, Jean Pascal, and now Gonzalez turned Beterbiev down, but it's still disappointing. How many rounds does the German last?
