The only way I know to watch it online is to buy it on TopRankTV.com. I watched Martinez vs. Chavez Jr. that way when I was out of town. I don't know if they are doing it for this fight or not.
But since you already paid for it that doesn't make sense for you. I don't think Comcast has an option to watch events away from home.
