The fight will be Alvarez’s first since his September victory over Kazakhstan’s Gennady Golovkin for the unified middleweight world title.
“Taking a big challenge in my career and representing the WBC as the 160 lbs champion, I will now fight for the world title for the 168 lbs vs Rocky Fielding, the current WBA champion,” Álvarez wrote on Twitter.
The 28-year-old Mexican will take a 50-1-2 record with 34 knockouts into the fight. Fielding, 31, is on a six-fight winning streak that improved his record to 27-1 with 15 knockouts.
He won the WBA super middleweight title with a technical knockout of German Tyron Zeuge in July.
