From NHL.COM OFFICIAL RULES SECTION:
http://www.nhl.com/ice/page.htm?id=26314
28.8 Restricted Area – A goalkeeper shall not play the puck outside of the designated area behind the net. This area shall be defined by lines that begin six feet (6’) from either goal post and extend diagonally to points twenty-eight feet (28’) apart at the end boards. Should the goalkeeper play the puck outside of the designated area behind the goal line, a minor penalty for delay of game shall be imposed. The determining factor shall be the position of the puck. The minor penalty will not be assessed when a goalkeeper plays the puck while maintaining skate contact with his goal crease.
Okay so now I'm all intrigued by this, because the rules don't clarify what happens with incidental contact. Is it at the referees discretion or is fully allowed because it's not included????
I don't think coincidental contact is called. The rules above say "play the puck" a few times. So I think the goalie has to make a shooting or passing motion with the puck.
If the goalie is outside the zone and a puck comes flying out of nowhere and accidentally hits him, it's not a penalty. He has to make a motion of some kind to play the puck.
I wonder what happens if a goalie kicks the puck. That's probably considered a playing motion.
Why can't the NHL just write enough articles to be more clear on these things. Too much "open to interpretation" stuff in there.
