On Saturday, these two teams will meet again with everything on the line in the Wild Card round of the AFC playoffs.
While they may wear the same jerseys and run the same plays, these are not the same teams that met back on September 13. They have both dealt with injuries and have different starters on both sides of the ball.
For the Chiefs, look no further than the offensive line, particularly that left side.
Left guard Jeff Allen missed the first six games of the season with a knee injury, and left tackle Eric Fisher played just one offensive snap in that game as he was working his way back from a high ankle sprain suffered at the end of training camp.
