What happens when an ice hockey player is injured?

• Timing: play stops when the injured player's team gains the puck, unless the other team is about to score.
• Serious injury: the referee or linesperson may stop play at once.
• Medical staff: may go onto the ice at a stoppage without waiting for permission.
• Substitution: a player attended to on the ice must be replaced until play resumes.
• Face-off: near where the puck was, with adjustments depending on which team had it.
• Injured and penalised: a teammate serves the time; the injured player may not play until it ends.
• Blood: off at the next stoppage until bleeding stops and the wound is covered; kit cleaned or changed.
• Goalkeepers: no extra time or warm-up; a replacement comes in at once if needed.
• Feigning injury: a minor penalty.

The glossary has the substitute goalkeeper, the goalkeeper, the penalty box, the diving, the faceoff and the referee.

Waiting for a change of possession keeps one team from losing an attack because of an opponent's injury. The blood rule protects other players from infection.
