10 key plays of the Colts' season: No. 6

The Indianapolis Colts couldn’t stop the Kansas City Chiefs through the first 33 minutes of the AFC divisional playoff game. And what made it even more embarrassing is that the Chiefs were without do-everything running back Jamaal Charles (concussion). They had racked up 38 points and quarterback Alex Smith looked like he was back at the University of Utah, beating opponents with his arm and feet.

Then, it happened.

Key play No. 6: Linebacker Robert Mathis pulls out his trademark move.

The Chiefs had the ball on second-and-6 at their own 46-yard line early in the third quarter when Mathis, standing up on the left side, shook off two blockers, chased Smith down from behind and chopped down on his arm to get the sack and the fumble. Linebacker Kelvin Sheppard recovered the ball and the Colts scored six plays later, as they continued their 28-point second-half comeback. The Chiefs only scored six more points, and the Colts' defense forced an intentional grounding and cornerback Josh Gordy did a good job defending receiver Dwayne Bowe on fourth down to clinch the game.
