Back in April of 2013, Nonito Donaire suffered the first defeat of his pro career when he lost a twelve round unanimous decision to Guillermo Rigondeaux in a super bantamweight unification.
Over the years, Donaire has fought as high as featherweight - winning a WBA world title in the weight class.
But in 2018, he decided to drop down by two weight divisions to the bantamweight limit of 118-pounds.
On Saturday night in Los Angeles, he will get the opportunity to capture a world title at his current weight when he challenges WBC champion Nordine Oubaali in a Showtime televised main event.
And then on August 14, also on Showtime, Rigondeaux - who last year also decided to drop down to the bantamweight division, will challenge WBO world champion John Reil Casimero.
Should they both win their upcoming bouts, Donaire is very interested in the possibility of avenging his first loss as a pro by facing Rigondeaux in a high stakes unification.
The bookies have tabbed Donaire as the underdog in his fight with Oubaali, while Casimero-Rigondeaux is viewed by many as a 50-50 fight.
Donaire indicates that his overall goal at the moment is to unify the entire bantamweight division. And if Rigondeaux captures the WBO title, the 'Filipino Flash' wants to get him in the ring.
“Without a doubt, if he can get past this tough fight [with Casimero], we will go for him. I'm coming to unify all the titles. I think that with the experience that I have added over these years [since we fought], I could knock out Rigondeaux. I have a lot plans and I am working for them," Donaire said to ESPN Deportes.
