NHL players could start participating in voluntary small-group workouts, and teams began opening their training facilities Monday.
Players learned Thursday training camps can open July 10, pending an agreement on returning to play later this summer.
Now, the players are expected to trickle back in preparation of the resumption of the season.
Players started skating by the handful this week in places like Boston, Chicago, Toronto, Pittsburgh, Columbus and Edmonton, while some teams waited to open their doors.
Veteran Nashville general manager David Poile said that while almost a dozen players remained in the area, the NHL has instructed teams not to ask or encourage players to show up because this stage is voluntary.
