Sergey Kovalev says he will no longer be 'Krusher Kovalev’ if he fails to get revenge over Eleider Alvarez this weekend.

Alvarez took the WBO Light-Heavyweight Title last August beating Kovalev in seven rounds, but the Russian immediately exercised a rematch clause.

They go again in Frisco, Texas on Saturday night in a fight that will be broadcast live on BoxNation with Kovalev’s career on the line.

It is another top quality fight on the Channel of Champions, with the bookies making Montreal based Colombian Alvarez a slight favourite.

Kovalev said: “This is the most important fight for me because I couldn't stop my boxing career as a loser. It's not in my character.

“First of all, this is my goal, to get back my belt that I dropped on the way to my big goals. I made a mistake last time against Alvarez, but this time I will fix it.

“This Saturday, I will fix this situation and be on top again. If not, I am not Sergey 'Krusher' Kovalev.”

Kovalev lost his invincibility tag in controversial losses against Andre Ward, but is hell bent on rediscovering the form that made him one of the most feared men in boxing during his pomp.

To get that esteemed tag once more he believes he must win the Alvarez rematch and then conquer the other 175lb Champions, Oleksandr Gvozdyk (WBC), Dmitry Bivol (WBA) and Artur Beterbiev (IBF).

“My goal is to collect all four belts, but I dropped this belt on my way to my huge goal,” Kovalev continued. After the Alvarez loss, a lot of people thought I should stop my boxing career. No, that's not in my character to stop my career by losing.

“When I win, I will think, stop or not to stop? But when I lose, it was 100 per-cent ‘no’.

Unbeaten Alvarez says he is fed up hearing Kovalev blame over-training for his defeat, and ordered him to stop bitching about the result.

Alvarez, 34, snapped: I believe that's a lot of excuses he's making. When you lose, you have a lot of excuses. I had a great game plan with my team. If he says that was an accident, then he needs to get ready for another accident.”

In other World Title action on the bill Oscar Valdez defends his WBO Featherweight Title against undefeated Italian Carmine Tommasone.

There is also a 10-rounder between hot prospect Teofimo Lopez and Diego Magdaleno, while a third World Championship clash features Richard Commey and Isa Chaniev squaring off for the vacant IBF Lightweight crown.

Ghana’s Commey lost a controversial decision against Robert Easter for the same beltin September 2016.

Like Kovalev, chances may be limited if he loses again and Commey admits: “I have to win this fight. No matter what, I have to win this fight. It means a whole lot to me. It's all about winning. That's it.”
