New slip resistant surface is seen just off the turf field inside the Edward Jones Dome before the start of an NFL football game between the St. Louis Rams and the Chicago Bears, Sunday, Nov. 15, 2015, in St. Louis. The surface has been added after San Francisco 49ers Reggie Bush slipped and fell during a recent game injuring himself on the uncovered, smooth surface underneath. (AP Photo/L.G. Patterson)
