Joseph Addai just found out what Steven Jackson, Mike Vick, and Clay Matthews learned previously - that the Redskins have a knack for injuring their opponents' most successful players.
As the Colts were driving down the field and eating up clock early in the fourth quarter, the Redskins forced Addai to fumble with the ball on the Washington 23-yard line. Addai had already been struggling with neck injuries, and a hard hit from London Fletcher required Addai to get some help leaving the field.
It was the crushing hit by Fletcher that caused the fumble after Kedrick Golston already had Addai wrapped up. The loose ball was recovered by LaRon Landry.
