Crawford will move up from welterweight to super-middleweight for this fight, adding 14 pounds to his frame. It's a big jump for Crawford, who's never fought at 168 pounds before.
Bill Haney, a respected boxing coach who helped his son Devin become the undisputed lightweight champion, has some concerns about the upcoming bout. He shared his thoughts with Pro Boxing Fans.
"Man, that's the biggest fight in boxing right now. Crawford stepping up … Listen, Canelo is big, and shoutout to Crawford stepping up, but does Crawford have to be worried about more things than just boxing? Absolutely. I didn't say he has to do any accusing nor will he do that but I'm saying is let's worry."
Haney's concerns stem from past experiences with doping issues in boxing. He mentioned what happened to his son Devin in a previous fight.
"If you watch what happened to Devin, Devin said the damage is done after the fight. You can never go and repair that. So let's be cautious, let's be prepared, and, at the very least, join 365 testing."
Haney's worries aren't unfounded. Last month, Francisco Rodriguez Jr, who trains with Canelo's long-time coach Eddy Reynoso, tested positive after beating Galal Yafai. Reynoso and Canelo have always said they're not involved in any wrongdoing.
Devin Haney himself had a similar experience. He lost a fight to Ryan Garcia, who used to train with Reynoso. The result was later changed to a no contest when Garcia tested positive.
The Crawford-Canelo fight promises to be huge. Both fighters are at the top of their game. Crawford's move up in weight adds an extra layer of excitement. But as Bill Haney points out, there might be more to worry about than just what happens in the ring.
