What is the restart if the ball bursts while not in play during a kick-off?

When the ball bursts while not in play during a kick-off, the match is restarted in accordance with the Laws of the Game. Specifically, this means that the referee would drop a new ball for the kick-off. Since the ball was not in play at the time of the incident and the kick-off had not yet been completed, the appropriate course of action is simply to initiate the kick-off procedure again.

It’s important to differentiate this situation from others where a ball becomes defective during active play, as those scenarios may lead to a different type of restart such as a drop ball. However, since the kick-off was not executed when the ball burst, restarting according to the procedures of a kick-off is the correct action.
