LANGHORNE, Pa. (AP) — Pop Warner is eliminating kickoffs in its three youngest football divisions, another safety-focused rules change sure to be noticed and discussed at higher levels of the game.

The ban, which will affect ages five to ten, will begin this fall. Instead, the ball will be placed at the 35-yard line to start each half and following scores.

The organization, which began in 1929 and has 225,000 children enrolled in football from ages 5 to 15, says it will review the results of the rules change following next season as it considers implementing the same ban in older age divisions.

Pop Warner has also announced a further reduction in contact time during practice, lowering the percentage to 25 from the 33 percent rule that was implemented in 2012.
