DE Jason Jones carted off field

LANDOVER, Md. -- Defensive end Jason Jones was carted off the field with a little less than six minutes remaining in the first half with a left knee injury.

His return is officially listed as questionable.

Initially, Jones had tried to walk off the field, but the trainers eventually called for the cart to help him off.

Jones has had knee injuries in the past, including going on injured reserve last season in Seattle.
