An October 22 fight between top bantamweight Nonito Donaire and super flyweight Omar Narvaez has been agreed to by the fighting parties, and HBO approval of the bout is all that stands in the way.

It would be surprising if HBO turned down the fight, as Narvaez (35-0-2, 19 KO) is at least the most highly-regarded of the list of unmarketable opponents presented to the network by Top Rank recently. Narvaez, 36, is a good boxer, but likely not near Donaire's level, and he's been a home fighter in Argentina for years, only occasionally leaving his base and never fighting in the United States to date.

Donaire (26-1, 18 KO) is probably fighting for the last time as a bantamweight before he moves up in search of bigger fights, with the ultimate goal right now appearing to be getting him to featherweight, where he could face the likes of Yuriorkis Gamboa, Juan Manuel Lopez, Orlando Salido, etc.

If HBO for whatever reason does not approve Narvaez, deals are reportedly in place for fights with Silence Mabuza and Christian Esquivel, two opponents no more credible or marketable than Narvaez.
