World Boxing Council President Mauricio Sulaiman was disappointed that his organization's champion, Saul 'Canelo' Alvarez, tasted defeat last Saturday night.

Canelo, who holds the WBC, WBA, IBF, WBO world titles at super middleweight, moved up to 175-pounds to challenge WBA light heavyweight king Dmitry Bivol.

Before a lively crowd at the T-Mobile Arena in Las Vegas, Bivol outboxed Canelo over twelve rounds to retain his title with a unanimous decision.

Canelo was a 5-1 favorite to overcome the unbeaten Bivol.

"Life is like that, just like boxing is: you win and you lose. The important thing is the ability to assimilate adversity, accept failure and have the maturity to get up and move on," Sulaiman told The Herald.

"This happened in September 2013, Saul entered the ring to face the one who was, at that time, the most important fighter [in the sport], Floyd Mayweather Jr. His personality led him to ask for that fight and the result was adverse, he lost the title and his unbeaten record.

"The greatest in history have lost: Muhammad Ali, Julio César Chávez, Sugar Ray Leonard, Marvin Hagler, Manny Pacquiao, Mike Tyson, in short, all these legendary boxers who were considered invincible were defeated. What happened after? They showed greatness by returning to build their legacy. 

"Canelo lost to Floyd and had the nerve to assimilate, accept is and rise up. He built new plans and ambitious dreams, worked and stayed with his team. He continued to learn, matured as an athlete and a person, and in the following nine years, since that failure, he achieved very important wins that elevated him to being the most important boxer [in the sport].

"Saul lost, he looked for a more dangerous challenge against an undefeated opponent and at a much higher weight; there is nothing to be ashamed of. I am sure that he will rest, meditate and, once again, assimilate, accept and, with maturity, return to the position that belongs to him. He still has a lot to give to Mexico, to boxing and to himself."

Canelo was already scheduled to have a trilogy fight with Gennadiy Golovkin in September - but he's currently considering a rematch with Bivol. There is an immediate rematch clause, which only Canelo can exercise.
