Name boxers who lost or got KO'd before they got big

[HtotheZ]

First one that comes to mind is Vitali getting KO'd in a kickboxing match when he was young.

Another one that comes to mind is Manny Pacquiao getting KO'd in like his 12th fight and TKO'd again about 20 fights later in his pro career. before all the barrera, morales and marquez fights.

Vitali has always been big. Dude is like 6'7.

Hopkins lost his first fight

Lots of guys, but the first that came to mind was Pacquiao. Manny got KOed a couple of times early in his career.
