Mondo Knows Facts
Hockey offside is judged at the blue line
An attacker cannot enter the zone before the puck crosses the line The blue line divides the rink into three zones, and a player is offside if both skates are across the line before the puck. The rule once required the puck to precede the player entirely, and it was changed in 2005 to allow a skate on the line. Video review can overturn a goal scored from a close offside. It sits in Mondo's sports collection, one of 200 facts that each trace back to the reference below.
