Update 2: I can confirm the other streams including redzone are still working and operating correctly via the NFL TV Truck. The games later today SHOULD work as they did yesterday. The issue today is that this games time was originally set for 7pm so the TV Truck was basically told to go on air at 4:30/5p ET instead of by 1p for game time. Obviously they are broadcasting it on TV so it is on and operational, but the stream output for online use is not working. NFLN is not working simply because too many people tried to use it at once. These streams should, and im 99% sure, should work for tonights games.
Update 3:
Here's some proof that this should work for tonights game. All the color bars are views and broadcasts for tonight, the two track broadcasts you see in bottom row are NBC New York and NBC Los Angeles, that black box in the middle is the NFLN stream which is down right now. All others are operational and working.
