(AP) - Chicago Bears receiver Johnny Knox was taken from the field on a cart with a mid-back injury in the opening minutes against the Seattle Seahawks and left the game.

Knox had just caught a pass from Caleb Hanie about four minutes into Sunday's game when Kam Chancellor poked the ball out of his hands.

As Knox made a diving attempt to retrieve the ball, he was hit by Anthony Hargrove and stayed down for close to 10 minutes while being tended to by medical personnel.

He was eventually placed on a stretcher and taken from the field on a cart, putting his hands over his face and wiggling his fingers as he left the field.

The Seahawks' Earl Thomas recovered the fumble at the Chicago 23.
