Welcome to the Black Friday edition of the Week 13 grades! After giving us a traditional feast of games on Thanksgiving, the NFL returned with its newest tradition: A Black Friday game. And it was a wild one with the Kansas City Chiefs holding off the Las Vegas Raiders 19-17 in a game that wasn't sealed until Nick Bolton recovered a Raiders fumble in Kansas City territory with just 11 seconds left to play.

As the Las Vegas Raiders and Kansas City Chiefs meet for the NFL's "Black Friday" clash, memories from their most recent holiday matchup still linger. The Raiders' 20-14 upset win on Christmas was more than a surprise -- it was a pivotal moment that reshaped the Chiefs' road to the Super Bowl.

NFL Week 13 rolls on with Black Friday football when the Las Vegas Raiders visit the Kansas City Chiefs today. Start time, schedule and where to watch.
