Which of the following is NOT a sign or symptom of a concussion that requires an official to remove a player from the game?

Visual impairment is not typically considered an immediate sign or symptom of a concussion that necessitates the removal of a player from the game. In the context of concussion recognition and management protocols, dizziness, confusion, and headache are commonly recognized symptoms that warrant concern. Each of these symptoms indicates a possible disturbance in brain function or an altered state of awareness, which is critical for the safety of the athlete.

Dizziness suggests a potential imbalance or issues with coordination, confusion reflects cognitive disruption, and headaches often accompany concussions, linking to increased intracranial pressure or other complications. On the other hand, while visual impairment can be significant in assessing neurological function, it is not categorized alongside these immediate symptoms that typically trigger the need for an official to act swiftly to protect the player.
