What Is Delay of Game in Ice Hockey?
What actions are considered delaying the game in hockey, and why are some situations automatically penalized?
Editor: Coach Mark • Updated: April 19, 2026
Short Answer
Delay of game is a penalty for actions that intentionally or unnecessarily stop or slow the game, such as shooting the puck out of play from the defensive zone.
Full Explanation
Delay of game occurs when a player or team causes an unnecessary stoppage or disrupts the natural flow of the game.
The most common example is when a player shoots the puck directly out of play over the glass from their defensive zone without it touching anything.
This results in an automatic minor penalty because it is considered a deliberate attempt to relieve pressure.
Other forms of delay of game can include freezing the puck unnecessarily, displacing the goal, or interfering with game procedures.
NHL vs IIHF Rule Differences
Both NHL and IIHF enforce delay of game penalties, especially for puck-over-glass situations.
The NHL applies a strict automatic penalty for this action, while IIHF may consider additional context in some cases.
However, the principle remains consistent: preventing intentional stoppages.
Common Delay of Game Situations
Delay of game can occur in several ways:
- Shooting the puck over the glass from the defensive zone
- Intentionally displacing the net
- Goalie freezing the puck unnecessarily
- Interfering with faceoffs or officials
Each situation is judged based on intent and impact on the game.
Why These Calls Are Controversial
Delay of game penalties are controversial because some situations appear accidental.
Fans may see a mistake, while referees apply strict rule enforcement.
Controversy usually arises from:
- Puck accidentally going out of play
- Pressure situations leading to mistakes
- Strict automatic penalties
- Game context
These calls often feel harsh but are applied consistently.
Edge Case: Deflection Before Leaving the Ice
A key edge case occurs when the puck deflects off a stick, skate, or glass before going out of play.
If the puck touches anything before leaving the rink, it is usually not considered delay of game.
If it goes directly out without contact, the penalty is applied.
This distinction is critical in decision-making.
IHM Signal System: How to Read the Situation
To identify delay of game, focus on these signals:
- Origin signal: Was the puck played from the defensive zone?
- Path signal: Did it go directly out of play?
- Contact signal: Did it touch anything before leaving?
Trigger-level rule:
If the puck is shot directly out of play from the defensive zone without any contact, a delay of game penalty is almost always called.
If there is any deflection, the penalty is usually not given.
IHM Insight: Why This Rule Is Misunderstood
Delay of game is misunderstood because fans often focus on intent.
The rule is applied based on outcome, not whether the player meant to do it.
Even accidental actions can result in penalties if they meet the criteria.
Understanding outcome vs intent is key.
