If an athlete suffers a possible spinal injury, it is important to: Encourage head rolls and other movement to prevent stiffness Monitor his or her heart rate Tilt the head back and feel around for broken bones in the neck Keep the neck and spine as still as possible

The correct answer is:<br /><br />**Keep the neck and spine as still as possible.**<br /><br />### Explanation:<br />If an athlete suffers a possible spinal injury, it is critical to minimize movement of the neck and spine to prevent further damage. Moving the head or spine could worsen the injury, potentially leading to permanent damage such as paralysis. Emergency medical services (EMS) should be contacted immediately, and the injured person should be kept as still as possible until professional help arrives.
