What action must the referee take when a wrestler is injured and requires an evaluation?

When a wrestler is injured and requires an evaluation, the referee's responsibility is to ensure the safety and well-being of the athletes involved. Extending the injury time as needed allows for a thorough assessment of the injury without the pressure of a ticking clock affecting the medical evaluation. This is crucial because rushing to determine a wrestler's condition can lead to inadequate care and potential exacerbation of the injury.

Injured wrestlers should be given sufficient opportunity to receive medical attention, and it's important for officials to prioritize health over the pace of the match. By extending the injury time appropriately, the referee ensures that the wrestler can be evaluated properly, which could involve checking for concussions, fractures, or other serious conditions that require careful assessment before deciding whether the wrestler can safely continue competing.

The other considerations involve limiting the time for evaluations or continuing the match without pause, which would not address the need for comprehensive care for the injured athlete. Therefore, extending the injury time is the most appropriate action for the referee in this situation.
