Canelo Alvarez defends his super middleweight undisputed championship in a trilogy fight against bitter rival Gennadiy Golovkin on Saturday at T-Mobile Arena in Las Vegas (DAZN pay-per-view, 8 p.m. ET).
Alvarez (57-2-2, 39 KOs), 32, defeated Golovkin in their rematch in 2017 by majority decision, a fight that followed a controversial split draw a year earlier.
After the rematch, Alvarez moved up in weight and won titles at super middleweight and light heavyweight, before losing to Dmitry Bivol last May challenging for Bivol's 175-pound WBA world title.
Golovkin (42-1-1, 37 KOs), 40, has been looking for the third fight with Alvarez since the rematch but had to wait four years. In that time, Golovkin went 4-0 with three KOs, including a ninth-round stoppage victory over Ryota Murata in April.
Also on the card, WBC junior bantamweight champion Jesse "Bam" Rodriguez defends his belt against Israel Gonzalez in the co-main event.
