Lengthy contract dispute with his promoter, followed by signing with 50 cent. He was also caught up in the Biogenesis Lab doping scandal.
Signed with 50 Cent and was bailed on an already set up fight with Brandon Rios so Top Rank weren't keen on him any more.
He saw the competition in front of him if he continued.
Truth is, he disapeared right when Adrian Broner called him and dissed him. Gamboa went into hiding since, thats all i gotta say.
He struggled with some not so great opponents so his promoters realized they can't sell a phenomena.
He also doesn't know much english so they can't sell his personality like Broner [who REALLY struggled with some nobodies].
He is scared to fight rios so fans lost interest with him...and he almost lost to farenas from philippines LOL...He is too cocky...
Because he has no chin and was afraid of Rios. He also was on PEDS.
idk, he lost his mojo?
At the pace he was moving a couple of years ago ,you would think he'd be a PPV attraction by now ,why does he seem to be so irrelevant these days?
