I suggest you get Justin.tv and cross your fingers, since it is rather hit-and-miss. Justin.tv is a live streaming app of Ustream broadcasts. It works great for tons of content, apparently the NFL as well. Slingplayer mobile or also direct tv's Sunday ticket will work too.
Or any of these other apps http://appadvice.com/applists/show/apps-for-the-nfl
