Matvey Korobov fights tonight on Pac-Cotto undercard. I Have a Question

[Mikhnienko]

So Matvey Korobov is on the Pacquiao - Cotto undercard for those who didn't know. Arum says it'll be shown for free before the actual PPV starts, so that's nice.

I got 2 questions i was hoping someone could answer.
How many rounds is the fight scheduled for?

And is Birmingham no longer his trainer? I read something that said Robert Garcia is his new trainer. Anybody know what is what?

It's a 6 rounder and his trainer is Kenny Adams.
