Boxing-Alvarez and Fielding set super middleweight bout for December

15 at New York's Madison Square Garden. 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," Alvarez 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. (Reporting by Gene Cherry in Salvo, North Carolina; Editing by Ken Ferris)
