Today, the only linemen who can receive a forward pass are the ends ( tight ends and wide receivers). Another change in rules occurred on January 18, 1951, which established that no center, tackle, or guard could receive a forward pass (unless such a player announces his intent to the referee beforehand that he will be an eligible receiver, called a tackle-eligible play). Illegal and experimental forward passes had been attempted as early as 1876, but the first legal forward pass in American football took place in 1906, after a change in rules. The development of the forward pass in American football shows how the game has evolved from its rugby roots into the distinctive game it is today. The forward pass is one of the main distinguishers between gridiron football ( American football and Canadian football) in which the play is legal and widespread, and rugby football ( union and league) from which the North American games evolved, in which the play is illegal. In several forms of football, a forward pass is the throwing of the ball in the direction to which the offensive team is trying to move, towards the defensive team's goal line.
