What is the correct restart after a player punches a teammate following a goal?

After a player punches a teammate following a goal, the correct restart is a kick-off. This is because when a goal is scored, the game is paused to allow for a restart at the center of the field. The kick-off is used to restart the game, and it occurs after a goal is scored regardless of events that take place just after the goal is netted.

In this situation, the actions of the player who punched the teammate do not change the fact that a goal has been scored, and the proper protocol is to perform a kick-off to resume play after the goal, rather than penalizing the team for that act. This allows the game to continue despite the incident, focusing on the result of the goal scored.

Other options such as an indirect free kick or a drop ball do not apply in this scenario, as they would typically be used for different violations or instances of play that do not occur immediately after a goal is scored. A free kick would also not be appropriate since the incident was not directed towards an opposing player but rather involved teammates. Thus, the kick-off is the most fitting and standard procedure following a goal, regardless of any infractions that may occur afterward.
