Boxers who retired undefeated but were not world champs

[X]

Didn't Tony Ayala Jnr 'retire' unbeaten when he was jailed for rape?

I think he came back on his release when he was about 40 and fought someone to a draw........ but I stand to be corrected?

He lost to yori boy campas

Oh, thanks ... was that after he came out of prison?
