The NBA and NBPA have announced that all three playoff games scheduled for Wednesday have been postponed.
Game 5 of each series will be rescheduled for a later date.
The Milwaukee Bucks began the movement by staying in the locker room ahead of their Game 5 against the Orlando Magic. The Magic, however, took the floor during warm ups before returning to their own locker room.
The Houston Rockets and Oklahoma City Thunder decided to go on strike as well shortly after the Bucks' decision became final. The Los Angeles Lakers and Portland Trail Blazers made a similar decision minutes later.
It is not year clear when the NBA will resume its schedule.
