For those in the US, you can catch both fights LIVE on EPIX. Online streaming at EPIXHD.com. They are also showing the Povetkin fight on the 25th.
And sooner or later the fights will most likely re-air on the MSG network. As they have with the Povetkin/Boswell and Helinius/Chisora fights. I believe there is some kind of lock in between the two networks because the crew that calls the fights are stationed inside MSG.
