Gamboa vs Lopez

[The Great]

Here's the BoxRec bio with four losses documented: Yuriorkis Gamboa - Boxrec Boxing Encyclopaedia One loss was an injury...

Here's his wiki. Shows that he at least 3 losses, as it documents 1 silver , and 2 bronze medals in his medal counts: Yuriorkis Gamboa - Wikipedia, the free encyclopedia

Again, point taken that he had a spectacular amateur career miles ahead of Juanma's, but just trying to be accurate...

Well then is over 400 mateur fights and only 4 defeats , here look , they said it on espn and I'm sorry I thought it was only 2 defeats , but like you said still a great amateur career. Here is the video where they said over 400 amateur fights : 1 minute and 45 sec in the video
