General Injuries
Assess the player on the field of play using the TOTAPS system:
Talk - What happened? Where does it hurt?
Observe - Look at the injured area. Is it different from the other side (swollen, a different colour, etc)?
Touch - Feel for swelling, tenderness and pain.
Active movement - Ask the player to move the injured part without assistance.
Passive movement - If the player moves the injured part actively, then carefully move it through a full range of movement.
