Are you a Denver Broncos fan? Question inside!?

So, does anyone know if the Broncos have a game at their home in Denver like, a week before Christmas? My brother's girlfriend is a HUGE fan, and she told me last night that my brother had recently told her to take the weeked off before Christmas and I know he wanted to propose to her at a Broncos game, and so I was wondering if they had a game in Denver them. If so, then I am going to be one happy sister who has been waiting forever for her brother to get married! :)
