It is looking uncertain whether this fight will happen. Pacquiao is being sued by his manager Audie Attar for breach of contract. Attar's company Paradigm Sports was negotiating a Pacquiao vs. Mikey Garcia fight when Pacquiao instead decided to sign a contract for the Spence fight.
I've just seen this news lately and I'm surprised what just happened. I thought that Pacquiao - Spence is already going to happen without any problems.
But an interesting surprise came out. Let's see how things will go for Pacquiao.
