It has been a long time coming. The only game of the Denver Broncos schedule that was not determined when the schedule was released was the Christmas weekend matchup with the Detroit Lions. The game was slated to be either on Saturday December 21st or Sunday December 22nd.
They ended up pushing back the announcement of when the game would be played. Funny thing is that shortly before it was announced, I had to try to figure for myself when it would be announced. But shortly after trying to get word on it, the NFL released the prime time week 16 schedule.
