Updated for today’s game (Aug 25th)-
Download the sopcost player here: http://download.sopcast.com/download/SopCast.zip
Once you get it all set-up, go here: http://streamednfl.blogspot.com/ and click the Redskins game.
It should load up.
NOTE: I have no idea about this sopcast player or how safe it is, so use at your own risk.
