For illegal checks to the head, start with NHL Rule 48: the available 2024–25 text says the head must be the main point of contact and the contact must have been avoidable. It does not make every instance of head contact illegal. Rule 50 is the rulebook entry for kneeing, but consult the current 2025–26 rulebook for its exact definition and penalty language. The NHL’s video explainers can help make both rules easier to follow.
Find the right rule in the current NHL rulebook
The NHL’s 2025–26 Official Rules list Rule 48 as “Illegal Check to the Head” and Rule 50 as “Kneeing.” The table of contents establishes those titles, but the full 2025–26 text could not be verified here. For the controlling wording—especially Rule 50’s definition and penalties—check the current rulebook rather than relying on a paraphrase.

The 2024–25 rule states: “A hit resulting in contact with an opponent’s head where the head was the main point of contact and such contact to the head was avoidable is not permitted.” The wording sets out two required parts: the head was the main point of contact, and the contact was avoidable. A clip showing head contact alone does not answer both questions.
#1 Best Overall
1. Identify the point of contact
Ask whether the head was the main point of contact, rather than incidental contact during a check otherwise directed through the opponent’s body. Where contact occurred is important, but the rule’s test is not simply whether the head was touched.
2. Consider whether the contact was avoidable
The rule identifies circumstances to consider, including whether the checker attempted to hit squarely through the opponent’s body, the opponent’s posture, and whether the opponent materially changed body or head position immediately before or at the time of the hit. These are contextual factors, not a single visual shortcut that decides every play.
3. Use more than one view of the play
A short clip or a single camera angle may omit the approach, posture, or movement that matters to the rule’s analysis. The NHL’s Rule 48 Video Rulebook explainer and its Department of Player Safety review of Rule 48 are useful companions to the written text.

How to read Rule 50: Kneeing
The 2025–26 rulebook contents identify Rule 50 as Kneeing, and the NHL provides a Rule 50 Video Rulebook explainer, dated September 23, 2024. For a specific play, use the exact wording in the current rulebook together with that explainer. The available material here does not establish the current Rule 50.1 definition, penalty provisions, or any automatic suspension rule, so those details should not be inferred from the rule’s title or from a video alone.

An on-ice penalty is an officiating decision during a game. Supplemental discipline is a separate league decision. For example, the NHL announced on April 17, 2025, that Jesse Puljujärvi received a two-game suspension for an illegal check to the head of Mitchell Chaffee. That case shows a suspension can follow an incident; it does not establish an automatic suspension—or an automatic on-ice call—for every play that looks similar.

A practical checklist for reviewing a play
- For a possible Rule 48 violation: locate the point of contact, assess whether the head was the main point of contact, and consider avoidability in light of the checker’s approach, the opponent’s posture, and any immediate material change in position.
- For a possible Rule 50 violation: consult the current Rule 50 text and the NHL kneeing explainer; do not substitute a guessed definition or penalty progression.
- For consequences: distinguish the officials’ in-game ruling from any later Department of Player Safety action.
