Clippers wanted to send a message of unity prior to the game starting.
Ahead of Game 4 against the Golden State Warriors on Sunday, the Los Angeles Clippers held a silent protest against owner Donald Sterling.
It is understood that the team held a meeting shortly after the audio recordings of Sterling making his comments were leaked, and decided upon acting together.
Before tip-off, the players came out on to the court and took off their warm-up shirts and threw them on the floor and left them there.
In addition, they had the rest of their warm-up gear inside out while a number of the players either wore black armbands, wristbands or socks as another sign of their discontent with the remarks that were made.
Over in Portland, the Trail Blazers joined their fellow professionals by all wearing black socks to rally against racial injustice.
No action has been taken against Sterling as of yet, but it is expected that NBA commissioner Adam Silver will make a statement prior to Game 5.
