From its earliest days as a mob game, football was a very violent sport. The 1894 Harvard-Yale game, known as the "Hampden Park Blood Bath", resulted in crippling injuries for four players; the contest was suspended until 1897. The annual Army-Navy game was suspended from 1894 to 1898 for similar reasons. One of the major problems was the popularity of mass-formations like the flying wedge, in which a large number of offensive players charged as a unit against a similarly arranged defense. The resultant collisions often led to serious injuries and sometimes even death. Georgia fullback Richard Von Albade Gammon died on the field from a concussion received against Virginia in 1897, causing some southern universities to temporarily stop their football programs.
