Canadian football

Canadian Football is a form of football in which two teams of twelve players each compete for territorial control of a field of play. Teams advance across the field through the execution of short, distinct plays, which involve the possession of an oblate spheroid ball (a direct descendant of a size 3 rugby ball). Players advance the ball by carrying it in the arms or passing it to another player (only one forward pass permitted per football play).

Canadian football is played at several levels in Canada. The professional league in which the sport is played is the eight-team [Canadian Football League]? (CFL).

The rules of the sport are very similar to [American Football]?, and the NFL has established a formal relationship with the CFL.
