Body checking

Body checking is a legal ice hockey tactic in which a player uses the body to impede an opponent who has possession of the puck or is about to gain it.

Ice hockey rules: The regulations governing play, equipment, penalties, and officiating in ice hockey. They define when body contact counts as a legal check.
Defensive zone: The end of the rink a team defends, extending from its goal line to the nearest blue line. Defenders use checks here to disrupt attacks and regain control.
Non-checking hockey: A form of ice hockey in which body checking is prohibited or substantially restricted. It provides a direct alternative to formats that permit body checking.
Concussion in ice hockey: A mild traumatic brain injury sustained during ice hockey, often through a blow or collision. Checks and related collisions can cause concussions despite being legal.
Angling (ice hockey): A defensive technique that guides an opponent toward the boards or away from a desired route. Angling can set up a check by narrowing the puck carrier’s options.
Forechecking: A team’s pressure on opponents in their defensive zone to regain the puck or disrupt a breakout. Forecheckers may use legal body contact to pressure puck carriers.
Cross-checking: An illegal check delivered with the shaft of a stick held in both hands and no part between them touching the ice. It distinguishes prohibited stick-based force from legal body contact.
Youth ice hockey: Organized ice hockey played by children and adolescents. Rules limiting checks in youth play are intended to reduce injury risk.
Puck possession: Control of the puck by a player or team during a game. Eligibility for a body check depends partly on the opponent’s relationship to the puck.
Board battle: A contest for puck control involving players along the rink boards. Body checks can initiate or decide these close-quarters contests.
