Boston Celtics guard Marcus Smart and big man Enes Kanter were among those in attendance at a Boston protest fighting racial injustice on Sunday.

Kanter addressed the crowd directly, saying those who chose to speak out and use their voices would be on the “right side of history.”

Smart, on the othe hand, said that he and other Celtic players in attendance chose to participate because they seek to emphasize the “truth.”

The 26-year-old added “justice hasn't been served” and pointed out that he and his teammates would keep fighting to obtain that justice.

Kanter teared up as he addressed the crowd, which is somewhat emblematic of his own personal struggles fighting against persecution.

The Turkish native has been among the most vocal critics of Turkish President Recep Tayyip Erdogan. He has spoken about becoming a “target” because of his opposition to Erdogan's regime.

Indeed, Turkish prosecutors sought an arrest warrant for Kanter in January of 2019.

Of course, while Kanter fights discrimination in his own country, he cannot relate to being an African-American like Smart and his other Celtics teammates.

Numerous members of the NBA community have taken part in rallies and protests in the last couple days following George Floyd's death in Minneapolis on Monday.

Celtics swingman Jaylen Brown — who is from Georgia — drove to Atlanta to help lead protests on Saturday.

The Celtics swigman also lobbied on behalf of three persons he said were wrongly arrested during the course of the protest.

Floyd's death has prompted a massive public outcry against racial injustice and police brutality. Multiple Celtics players like Marcus Smart and Enes Kanter are joining their peers in using their platforms to call for change and reform.
