List of gridiron football rules
The first documented indoor football games were those played at Madison Square Garden in 1902 and 1903 known as the "World Series of Pro Football." They were the first efforts at a national professional football championship. The games were played on a 70-yard by 35-yard dirt field but otherwise adhered to outdoor rules. Poor attendance led to the tournament being discontinued for 1904. Madison Square Garden had to be redone to accommodate the teams. The wooden flooring of the arena was removed and replaced by an earthen surface. The goal lines were only 70 yards apart and the playing field was only 35 yards wide. (Since was in the era before the forward pass, there were no end zones, as they had not yet been invented.) The earthen surface became sticky as the game progressed and made for some tough maneuvering, while the stands were right up to the playing field and proved to be a physical hazard. The kicking game was also drastically affected. In a game on a normal field, the team with the longest punts had the advantage. However, the Gardens proved to be a dream for a weak punter, due to the field size. Also the arena wall was right on the edge of the field, presenting a serious hazard on any sideline plays. One player knocked himself out of the tournament by running into the wall on the opening kickoff.
