World Boxing President Mauricio Sulaiman has praised the latest move by Canelo Alvarez, who will follow up his middleweight world title win over Gennady Golovkin by taking on Britain's World Boxing Association "regular" super middleweight champ Rocky Fielding in New York in December.

"I'm very excited to announce my next fight," Mexico's Canelo tweeted Friday, revealing the bout will be held at Madison Square Garden.

"Next December 15th at the New York MSG. Taking on a big challenge. I will fight for the world title at 168 pounds versus Rocky Fielding, the current WBA champion!"

Canelo ended Golovkin's unbeaten reign as unified middleweight champion with a majority decision in Las Vegas on September 15, seizing the World Boxing Council and WBA middleweight belts.

Fielding, 31, became the WBA's "regular" world champion in the super middleweight division in July with a knockout victory over Tyron Zeuge -- although the WBA recognizes fellow Briton Callum Smith as the "super" champion in the division after Smith's knockout of George Groves in Saudi Arabia in September.

At the recent WBC convention in Kiev, the World Boxing Council granted Canelo's request to make a voluntary defense - which the sanctioning body approved.

Sulaiman has embraced Canelo's move to fight Fielding at a higher weight, which in victory would make the Mexican superstar a three division world champion. 

"It's an opportunity that came up [for Canelo] and it's going to be a spectacular close to the year. The WBC is in full support [of his decision] because we have agreed to that," said Sulaiman to ESPN Deportes.

"We are living in a different world. I am happy because Canelo is at home (with the WBC). We agreed on this fight taking place at 168 pounds, he will represent the WBC."
