The NBA board of governors on Wednesday voted to approve tougher resting policy rules and punishments for star players who sit out games — including those on national TV and in-season tournaments — as well as multiple All-Stars sitting out together in regular-season games, a source told ESPN.

Teams must refrain from any long-term shutdown — or near shutdown — when a star player stops participating in games or plays in a materially reduced role in circumstances affecting the integrity of the game, per a memo obtained by ESPN.

The rule would ultimately give the league office authority for greater oversight over discipline for missed games and an ability to fine teams over $1 million for each instance of violating resting rules, sources said.

As the league negotiates a new media rights deal, NBA commissioner Adam Silver has been determined to increase player participation, and the league’s goal is to strengthen the initial player resting policies that were adopted in the 2017-18 season and new rules that mandate players participate in 65 regular-season games to be eligible for postseason awards.

The NBA is defining a star player as someone who’s made the All-Star or All-NBA teams in any of the three previous seasons, sources said.

The NBA will incorporate a fine system for teams that begins with $100,000 for first offenses, $250,000 for second offenses and $1 million more than the previous penalty for each additional fine, sources said.

A league memo obtained by ESPN about the changes describes these areas of the new policy. Enforcement of these policies will be based on league office investigations, which will include independent medical reviews, sources said.
