Bud, 38, fought and defeated the Mexican boxer, 35, last month in their super-middleweight clash in Las Vegas, and Crawford has now detailed the gruelling talks he had to sit through in order to get the bout to happen.
During an appearance on the All The Smoke Fight podcast, Crawford said: “They brought me in there, we went into a little back room and we were there for like nine hours. Going back-and-forth.
“They weren't budging, I wasn't budging.”
Bud was then left to finalise the terms of the match by himself, without having any help from his legal team.
He explained: “We finally came to terms. That day, everything happened that day.
“It wasn't the agreement that they wanted, it wasn't the agreement that I wanted. It was kind of in the middle.”
Saudi boxing promoter Turki Alalshikh was initially reluctant to back a Crawford–Canelo fight, but once Canelo signed a four-fight deal with him, the matchup became inevitable.
Canelo dropped his planned bout with Jake Paul, 28, to face William Scull, 33, in May, winning by unanimous decision before starting camp for the highly anticipated clash with Crawford.
With Alalshikh’s approval secured, Crawford then entered nine hours of negotiations to finalize the fight.
Bud’s unanimous victory over Canelo was historic, seeing Crawford become the first boxer in the modern era to hold undisputed titles in three weight divisions.
Reflecting on his win, he said: “It feels great. I'm just sitting back, enjoying my victory. It definitely was one of the greatest moments of my career.”
Crawford - who moved up two weight classes to face Canelo - added he may move back down a weight class for his next fight.
He teased: “I’m going to sit down with my team, and we are going to discuss what is next in the future for Terence Crawford. Who knows? I might go down to 160lbs.”
When asked whether this victory was the greatest moment of his career, Crawford said it was “tough” to say, as becoming the undisputed light welterweight champion in 2017 also holds special meaning to him.
He said: “This moment [beating Canelo] was huge, but something about that first one – this little poor kid from Omaha, Nebraska, set his sights out to be a world champion and had to travel all across the world to become world champion.
“And on one night, all of the dreams came true. Those two moments are definitely special.”
