LOOK at the player and the location of the injury. Try to assess the player's response to the injury and whether the response is in proportion to the injury or not.
Location and appearance: Try to first assess if the injury is mild, moderate or severe.
Ask yourself: Is the injury a simple injury that requires simple cleansing, and a bandage? Or, is it associated with a joint where they may be additional structures injured? Even if the injury looks mild, consider if the injury involves the structures of the face (mouth, eyes, nose, and ears), head, chest (cardiac), abdomen (spleen, kidney), and genitalia (testicles); special considerations need to be taken. Remember to apply P.R.I.C.E.S. as necessary.
Be mindful anytime the pain experienced by the player is disproportionate to the mechanism of injury.
R: Rest the player
I: Apply ice to the area of bruising
C: Compression wrap or apply pressure if necessary
E: Elevate
Notify parents and encourage physician evaluation if you feel uneasy about the injury.
