I really don't know how the whole contract thing work legally but it seems that it is possible, even if you sign a contract, to sign with another promoter and to get away with it, a bit like what happened between Golden Boy and Top Rank with the pacman. If I remember well and that the information I had was correct, Top Rank's contract with Pacquiao was expired when he did sign with Golden Boy and still, Arum has been able to roll him back in his stable, how's that? If it has been possible and that there is no funny clauses that I wasn't aware of, I think that Donaire might well be able to remain with Golden Boy.
