It might be Monday morning, raining and nearly freezing in Kansas City ... but Chiefs fans are still pouring out in droves to support their team before their huge matchup with the Philadelphia Eagles.
According to reporters at Arrowhead Stadium, Patrick Mahomes fanatics showed up to the site of arguably the biggest game of the NFL's regular season some 12 hours before it began ... this despite it being a workday with some pretty crappy weather.
You can see in images taken by KCTV5's Nathan Brennan, a line of cars filled with Chiefs fans stretched all the way into the street outside the stadium -- even though it's about 40 degrees out.
Plenty more are expected to be on their way soon, too.
Of course, it's hard to blame them for the excitement ... after all, the "Monday Night Football" matchup features two of the best teams in the league -- and it's also a rematch of Super Bowl LVII.
The Chiefs are currently 2.5-point favorites ... though many believe the Eagles -- who are 8-1 this season -- are the better squad.
Kickoff is slated for 8:15 PM local time ... getcha popcorn -- and, for those in K.C., your umbrellas and mittens -- ready!!
