The recommendation to adopt 3-on-3 play in regular-season overtime next season dominated the news Tuesday at the meeting of NHL general managers here, the suggestion that a limited video-replay challenge be instituted for next season could be as important.

The replay challenge, as proposed, would be used to rule on goals that involve the question of goaltender interference, or on delay-of-game penalties for players in the defensive zone shooting the puck directly out of play.

"What we're going to do, which is different, is we're going to create access for the officials on the ice to actually see video in consultation with the Situation Room in Toronto and they're going to look at it and they're going to see if, with the benefit of review, after a coach's challenge, whether or not there was a better call to make," NHL Commissioner Gary Bettman said.
