Canelo Alvarez to face Golovkin in long-awaited trilogy Sept. 17 before rematching Bivol

The sport's biggest star will face his all-time rival in his next fight.

Canelo Alvarez (57-2-2, 39 KOs) announced Monday that he plans on defending his undisputed super middleweight world titles against Gennadiy Golovkin on September 17. If successful, Alvarez will exercise his contractual right to a rematch against Dmitry Bivol, who soundly outpointed him for the WBA 175-pound world title on May 7 in Las Vegas.

"In the next few days, we will announce the September fight," Alvarez stated. "Surely, it will be against GGG because we already had that agreement, but I will also fight [Dmitry] Bivol again [after that]."
