Colts defensive end Justin Houston was all too eager to show his old team he could still play.
And he made the plays that helped his new team pull a significant upset.
Houston was named AFC defensive player of the week for his big game in his return to Kansas City.
He had a sack and two tackles for loss, including the fourth-quarter stuff of Damien Williams to clinch the win.
The 30-year-old Houston helped key a defense that was missing its best player (Darius Leonard) and both starting safeties, making the win that much more impressive.
