Unless you have Directv, you won't get an games on TV except MAYBE the local New York Dragons game if MSG is covering it.
If you go to
http://www.arenafootball.com you'll find information for AFLNet, which broadcasts a few games a week normally, but I think this week they're not doing anything.
If you want more or less updated information, you can come to
http://www.arenafan.com, register as a user, then join the ArenaFan chat room
http://www.arenafan.com/chat where myself and a whole bunch of other people keep everyone up to date on the games going on at the moment (AFL and af2).
Tonight there are SIX games at the same time. I know the Dallas/Philly game is on Directv somewhere and so is one other game. I'll be doing pbp of the Tampa Bay/Orlando game tonight in the chat room until about 5:00 left in the game (I'm media, and have to go to postgame interviews), and people should be at least scoreboard watching if not listening to the various online radio links to keep us all up to date.
