Can I order the Pacquiao vs Mosley fight tomorrow?

I don’t know if the fight is being offered on demand or whatever so I can order it. I heard that Showtime is airing the fight instead of HBO this year. Is there anyway I can order the fight even though I do not have Showtime? My cable company is Chart Communications in NE Connecticut. Any good advice is appreciated. It’s going to be a great fight and I do not want to miss it!
