General managers around the league discussed the potential of having a challenge system for coaches during a meeting on Tuesday, according to Zach Lowe.
Discussions surrounded whether coaches should be able to challenge "black-and-white rulings" such as out-of-bounds plays and goaltending, but not fouls.
While specific details will still have to be ironed out, the topic has gained a new momentum, according to Lowe.
Lowe added that having a "replay official" at the scorer's table to trigger reviews without stopping play was another topic of discussion during the meeting.
