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.

A mistimed snap by Las Vegas rookie center Jackson Powers-Johnson with just seconds left denied the Raiders an opportunity to kick a potential game-winning field goal

The Chiefs clinched a playoff spot with the 19-17 win over the Raiders that was sealed by a bizarre game-ending fumble.
