Canelo Alvarez and Caleb Plant agreed to a November date for their pay-per-view fight, according to ESPN's Mike Coppinger.
Coppinger reported in July the two sides were close to an agreement for a September event before reaching an impasse.
The stakes couldn't be much higher in November. Alvarez is the WBO, WBA and WBC super middleweight champion, and Plant is the only person standing between him and undisputed status within the division.
Alvarez earned a technical knockout of Billy Joe Saunders in his last fight in May, which brought him the WBO gold. Immediately after the victory, he made it clear Plant was in his crosshairs:
The 31-year-old sports a 56-1-2 career record, his lone defeat coming against Floyd Mayweather Jr. in September 2013.
Plant is unbeaten with 12 knockouts in 21 fights. His last bout was a unanimous-decision victory over Caleb Truax in January, which was his third successful IBF title defense.
Defeating Canelo would be a star-making moment for Plant, along with making him the undisputed super middleweight king.
Alvarez, meanwhile, might be looking at more than Plant's IBF championship.
Coppinger reported that Alvarez and Premier Boxing Champions, which manages Plant, signed for one fight. The agreement could open the door for Canelo to take on more PBC fighters, most notably super middleweight challenger David Benavidez or WBC middleweight champion Jermall Charlo.
