The NFL BLOCKED the CHIEFS vs CHARGERS WEEK 3 HIGHLIGHTS and as a result, that game is not featured in this highlights video.
To be fair though, I'm not too sure there are very many Chiefs fans who are happy about revisiting that game.
If you ARE, however, in the minority, that individual game highlight can be found here:
   • Kansas City Chiefs HIGHLIGHTS vs. Los...  
(for reasons I do not know, that video isn't blocked. makes sense.)

Another year, another Chiefs highlight video to hype ya'll up for the playoffs. GO CHIEFS!!
