CHICAGO (AP) Head linesman Ed Walker has been taken from the field on a cart after he slipped on the Soldier Field grass during Monday's game between the Minnesota Vikings and Chicago Bears.
Walker was injured running down the Vikings' sideline as the Bears punted. His legs bucked, and he was tended to for several minutes by medical personnel before being placed on the cart. He gave the thumbs up sign as he left the field.
