Video review and coach's challenge in ice hockey
IIHF hockey uses video review to check certain plays, especially scoring situations. A coach's challenge is a separate team-initiated process. This guide explains the difference and why available reviews can depend on competition technology.
Video review is not the same as a challenge
Under IIHF Rule 37, designated video officials can review goal situations. Rule 38 covers coach's challenges. A review can therefore happen without a team challenge.
What coaches may challenge
IIHF events can allow challenges for offside before a goal, missed attacking-zone stoppages leading to a goal, goalkeeper interference, and some puck-over-the-glass delay-of-game calls. The exact set depends on the event and its technical setup.
What happens after a goal
IIHF goal-review procedures can hold the next face-off while a scoring play is checked. At events using coach's challenge, teams have a defined goal-break window to decide whether to challenge. The on-ice referees make the final ruling with video support.
Why competition rules matter
Camera coverage and video-review capability are not identical at every IIHF event. A challenge available in one tournament may be unavailable in another setup, so the current IIHF rules and the competition regulations control.
