It’s hard to imagine, but up until the 1920s the forward pass was an illegal play in Canadian football. Early Canadian football resembled the game of rugby more than the pass happy version of gridiron football we are accustomed to watching today.
The forward pass, a staple offensive play in gridiron football, was first introduced in American football in 1906. Illegal and experimental forward passes were seen in the Canadian game over a decade later.
It wasn’t until 1929 that the Canadian Rugby Union formally allowed the use of the forward pass. Eastern teams didn’t use it right away, however. The first official completed* forward pass in Canadian football was thrown on Saturday, September 21, 1929 in Edmonton in a game between the Edmonton Eskimos and the Calgary Tigers. Calgary player Gerry Seiberling (pictured below) threw the historic pass to Ralph Losie. Calgary won the game 33-8.
*The first legal attempted forward pass was actually thrown earlier in the day in a game in Winnipeg. The pass by Norm McLeod’s (St. John’s) was intercepted by Ronnie Gay (Tammany Tigers) in the first quarter of the game.
