The Milwaukee Bucks' owners backed the players' decision to boycott their NBA playoff clash against the Orlando Magic.
All three NBA playoff games on Wednesday were postponed amid protests following the shooting of Jacob Blake in the United States.
The decision was taken after the Bucks made the call to boycott Game 5 of their first-round playoff series against the Magic.
Bucks owners Marc Lasry, Wes Edens and Jamie Dinan supported the players, although acknowledged they were unaware of the plans.
"We fully support our players and the decision they made," a statement from the owners read. "Although we did not know beforehand, we would have wholeheartedly agreed with them.
"The only way to bring about change is to shine a light on the racial injustices that are happening in front of us. Our players have done that and we will continue to stand alongside them and demand accountability and change."
The vote of confidence from Bucks ownership was followed by a statement from the NBPA, which added it will stand behind the player strike indefinitely.
"Throughout the season restart, our players have been unwavering in their demands for systemic justice," NBPA executive director Michele Roberts said in a statement. "This week we witnessed another horrific, shocking and all too familiar act of brutality in the shooting of 29 year-old Jacob Blake in Kenosha, Wisconsin.
"The Players have, once again, made it clear - they will not be silent on this issue. We stand with the decision of the players of the Milwaukee Bucks to protest this injustice and support the collective decision to postpone all of today's games."
The Bucks lead their series against Orlando 3-1, but the season is reportedly in jeopardy as players demand change amid protests against police brutality and racial injustice in the USA.
