VIDEO: Extra ambulances were summoned to Lambeau Field Sunday because heat was affecting large numbers of fans at the Green Bay Packers-Cincinnati Bengals game. Authorities requested three additional ambulances about 4:45 p.m. The exact number of heat-related calls was not available as the game's second half began, though the volume of police radio traffic regarding heat issues was clearly higher than in recent memory. Green Bay Metro firefighters and city police were running from call to call during the game.
