Missing fights from BoxRec / Official records:

I've noticed for awhile that BoxRec is great about getting amateur losses for top guys, but terrible about getting their wins. No idea why other than that maybe they're better documented typically

 

I believe many old-time fighters have a ton of fights missing. This is not surprising. And some of these "Debut" fights are pure nonsense, in my opinion. I do not blame BoxRec for that. It would take an enormous amount of digging to uncover the missing fights, and I doubt even then if all of them could be recovered.

 

Was researching Joseph "Jusuf Saalam / Henry Hank" Harrison earlier and according to multiple sources he lost a ten rounder UD to Claude Herman "Humphrey" McBride, but it isn't on either of their BoxRec pages. I think there are a lot more gaps than we realize, despite the longtime painstaking efforts of many historians and editors that have contributed at BR.

I think the more modern you get, the fewer omissions there are going to be, though. Outside maybe an obscure small hall show in Paraguay or Mongolia or Ghana here and there never getting updated into the database.

 

Not just Canelo. Other Mexican fighters have had missing fights. I remember around 2014 that Juan Francisco Estrada suddenly had a couple of wins added to his record, something like 3-4 wins.

 

They lack the resources to verify the more obscure fights. And from my understanding, boxrec does try to hold a high standard, so if they can´t be for certain then the fights wont get listed.

In MMA there are several sites that try to meticulously record fights. They have had a real though time in verifying the legitimacy of the more obscure cards. And some guys have lied their way through them to the UFC even.

My amateur fights are recorded in my and my opponents boxing passports. I don´t see how anyone at boxrec could ever get access to this info without I or the opponents handing over our passports.
