What happens if a player accidentally displaces the jack while it is at rest?

When a player accidentally displaces the jack while it is at rest, the correct procedure is to have the opposing skip reposition the jack. This action ensures that the game continues smoothly and that the jack is put back into play in a manner that is fair and consistent with the rules. The opposing skip is tasked with this responsibility because they are most often considered as the representative for the team in deciding how to proceed when such incidents occur.

This process maintains the integrity of the game and allows both teams to have a sense of fairness, as it is the opposing team that can assess the situation and decide where the jack should be placed. This ensures that no advantage is given to either side from an unintentional mishap.

In context, the other options do not align with the established rules of the sport. Leaving the jack where it is until the end of the game would invalidate the rules that govern play, while requiring the player to replace the jack themselves could lead to unfair advantages and conflicts. Similarly, pausing the game for a decision is unnecessary as the protocol for repositioning the jack is clear and established.
