What happens if kickoff goes through goal post?

Answer 1

If a kickoff goes through the goal post without being touched by a player, it is considered a touchback. In American football, a touchback occurs when the ball is kicked into the end zone and the receiving team chooses not to advance it out. The receiving team then starts their offensive drive at their own 25-yard line.

Answer 2

If the kick from a kick-off goes directly between the opposing team's goal posts under the crossbar, then a goal is scored. If the same happens against the kicker's own goal, then a corner kick is awarded instead of a goal.

Answer 3

Nothing. It is a touchback
