You can watch the said episode below as provided by CBS/SHO Sports via their channel on Youtube. I am really glad that this channel are really willing to give the fans and boxing enthusiasts a great sports entertainment as they allow everyone without country restrictions to watch the episode. A move that I believe that is the best for Pacquiao vs. Mosley promotion which is not done on the other network / channel the handle the previous big matches like this.
If you want to watch Pacquiao vs. Mosley online live later, just return here for details on where and how to do it. But you could start by getting a PPV subscription from your local TV channels or get the online streaming from TopRank.
