In a correspondence to players addressing the uncertainty surrounding the NBA's indefinite suspension of play, the National Basketball Players Association on Friday spelled out terms of a doomsday provision included in the collective bargaining agreement that could free owners from paying players a percentage of their salaries should the rest of the season be lost to the coronavirus pandemic.

The CBA includes a clause called the force majeure event clause that includes multiple dramatic scenarios -- including epidemics -- that the league could trigger in the event of a worst-case scenario. Other instances that could trigger the clause include natural disasters and war.

The next scheduled paycheck for players comes on Sunday, and those will be fulfilled.

Sources say there's been no discussion among the league and NBPA about triggering that provision -- especially because there remains hope that the season can be resumed with completion of a postseason that could be pushed back into midsummer.

In the email, the union told players that there had been no discussion with the league on the provision.

According to Article XXXIX, Section 5 in the CBA, players lose 1/92.6 of their salary for every game missed as a result of a force majeure event -- this refers to events or conditions that make it impossible for the NBA to perform its obligation under the CBA.

Commissioner Adam Silver said he plans for the NBA to miss a minimum of 30 days before it can even begin to hope for a resumption of play.
