Injuries
- allows play to continue until the ball is out of play if a player is only slightly injured
- stops play if a player is seriously injured and ensures that the player is removed from the field of play. An injured player may not be treated on the field of play and may only re-enter after play has restarted; if the ball is in play, re-entry must be from the touchline but if the ball is out of play, it may be from any boundary line. Exceptions to the requirement to leave the field of play are only when:
- a goalkeeper is injured
- a goalkeeper and an outfield player have collided and need attention
- players from the same team have collided and need attention
- a severe injury has occurred
- a player is injured as the result of a physical offence for which the opponent is cautioned or sent off (e.g. reckless or serious foul challenge), if the assessment/treatment is completed quickly
- a penalty kick has been awarded and the injured player will be the kicker
I guess the 'completed quickly' is a subjective decision, if people are determined to include it as a mistake they can argue that point.
