    • If the player is deemed by the on-site Athletic Trainer to not have suffered a concussion, the player may re-enter the match at any stoppage of play and must replace the original substitute; this head injury evaluation will not count as a substitute moment.  
    • If the player is not cleared to return to play by the on-site Athletic Trainer, the replacement player will no longer be considered a temporary substitute.
