An official was carted off the field during the first quarter of Monday's game between the Minnesota Vikings and Chicago Bears after he suffered an apparent leg injury on a punt.
Head linesman Ed Walker slipped onto his backside away from the play while running on the grass at Soldier Field. Medical personnel fitted an air cast around his left leg before he was carted off the field.
Walker's injury occurred with a little more than five minutes left in the first quarter of the Bears' 20-10 victory.
Referee Gene Steratore's crew finished the game with six officials.
