Other Flex game options: Vikings-Bengals Bears-Browns Steelers-Colts Falcons-Colts
All of these games are labeled as flex games for 12/16 or 12/17. Not sure if there is a Saturday night game on 12/16, but the rest of the options seem like bad options.
Bronco fan here, been watching closely for the final scheduling news of NFL Network’s Tripleheader on Sat. Dec. 16. I too think Denver@Detroit will be the nightcap on that Saturday at 8pm ET. On the Rich Eisen Show recently, I heard him say that Broncos-Lions would be a very juicy game for NFL Network if they can get it and that he hopes he can do the play by play. As another poster noted, it will likely be announced on Tue. Dec. 5.
