The NHL Players' Association executive board, comprised of player representatives from all 31 teams, will meet in Chicago on Sept. 4 for a CBA update discussion, according to TSN's Pierre LeBrun.

Other players will also attend the meeting, LeBrun notes.

The NHLPA has until Sept. 15 to opt out of the current collective bargaining agreement, which is scheduled to run through the 2020-21 season. The NHL has until Sept. 1 to make its own decision on the matter.

The two sides have held multiple meetings throughout the summer, LeBrun adds, but it's unclear how much progress has been made.

Both parties will look to avoid a labor stoppage after failing to do so during each of the previous two negotiations. The NHL lost an entire season in 2004-05 and convened a 48-game campaign in 2012-13 after the league and the NHLPA reached an agreement in January 2013.
