TORONTO -- In his first game back following the NBA鈥檚 COVID-19 shutdown, Toronto Raptors star Kyle Lowry was asked about his team鈥檚 decision to kneel during the Canadian and U.S. national anthems.

鈥淭o be down there for four straight minutes 鈥 to think about another human being kneeling on another human being鈥檚 neck for eight minutes and 46 seconds, that鈥檚 a bad thought to have, an unbelievable messed up thing that that man did to an innocent Black man,鈥 Lowry told reporters following the game, referring to the death of George Floyd.

For weeks, NBA players such as Lowry have been speaking out following a series of police shootings of Black people that sparked wider conversations about racism and injustice. Almost every player in the league has added a racial justice-themed call to action on the back of their jersey, and the words 鈥淏lack Lives Matter鈥 are emblazoned in capital letters across the basketball court.

In the boldest move yet, the Milwaukee Bucks -- the NBA鈥檚 top team -- decided Wednesday to boycott Game 5 of their playoff series against the Orlando Magic to protest the shooting of Jacob Blake, a Black man who was shot in the back multiple times by police in Wisconsin as he tried to enter a vehicle with his three children inside.

Blake, 29, survived the shooting but is now paralyzed from the waist down, his lawyer says.

After the Bucks鈥 boycott, the NBA postponed all three of Wednesday鈥檚 playoff games.

On Tuesday, the Raptors met with the Boston Celtics to discuss the possibility of boycotting Game 1 of their upcoming Eastern Conference semifinal series, scheduled for Thursday. A decision has not been finalized.

Here鈥檚 a look at how NBA players and coaches have spoken out about racial injustice.

Fred VanVleet, Toronto Raptors player

Jersey message: Black Lives Matter

Fred VanVleet says that, following Blake鈥檚 shooting, basketball is the last thing on his mind, about the upcoming game.

"You know, coming down here and making a choice to play was supposed to not be in vain, but it's just starting to feel like everything we're doing is going through the motions and nothing's really changing," VanVleet said.

"Here we are today with another unfortunate incident, so my thoughts today are with that man and his family and trying to wrap my mind around what they're going through."

He also expressed frustration that the onus is on Black men, like himself, to lead a difficult conversation even as more people get shot.

"At what point do we not have to speak about it any more?鈥 he said.

"Are we going to hold everybody accountable, or are we just going to put the spotlight on Black people or Black athletes or entertainers and say 'What are you doing? What are you contributing to your community? What are you putting on the line?鈥'

LeBron James, Los Angeles Lakers player

Jersey message: None

Basketball legend LeBron James is one of a handful of players in the league who hasn鈥檛 added a Black Lives Matter message on the back of his jersey. The reason, he says, is because he preferred to pick his own slogan rather than pick from a pre-approved list provided by the NBA, which included Black Lives Matter, Equality, Say Her Name, See Us, Listen and Education Reform.

Several players expressed frustration that the NBA鈥檚 list of slogans did not include the word 鈥減olice.鈥

Regardless, James has been vocal in interviews and on social media about the reckoning on race. Following Blake鈥檚 shooting, James tweeted 鈥淔鈥- THIS MAN!!!! WE DEMAND CHANGE. SICK OF IT.鈥

He鈥檚 also spoken candidly about what it feels like to encounter the police as a Black man.

鈥淚 said it, I know people get tired of hearing me say it, but we are scared as Black people in America. Black men, Black women, Black kids, we are terrified,鈥 he told reporters in a recent post-game interview.

鈥淏ecause you don鈥檛 know, you have no idea, you have no idea how that cop that day left the house. You don鈥檛 know if he woke up on a good side of the bed, you don鈥檛 know if he woke up on the wrong side of the bed.鈥

Stephen Curry, Golden State Warriors player

Jersey message: Equality

Stephen Curry has taken his activism beyond basketball, having recently worn a pair of golf shoes with Breonna Taylor鈥檚 name on them during the American Century Championship.

Taylor, a 26-year-old Black woman, was shot eight times by police in her apartment after officers executed a no-knock search warrant and exchanged gunfire with her boyfriend.

Curry has spoken about what it鈥檚 like to be seen as a 鈥渞ich, successful鈥 Black person, and says white people need to do more to call out subtle racism.

鈥淚f another white person hears that comment, they're going to think the same thing. And it's not going to trickle down to anybody else and be able to create opportunities for somebody else to get that in that room and prove their value. Prove their worth,鈥 he said.

鈥淲hatever it is, to do the right thing, no pun intended, but to see everybody as equal and that's all we're asking for.鈥

Doc Rivers, Los Angeles Clippers coach

Doc Rivers has directly called out U.S. President Donald Trump, who has tried to characterize anti-racism protesters across the U.S. as a group of violent radicals who pose a threat to suburban America.

Rivers, who wore a face mask that read 鈥淰OTE,鈥 held back tears as he accused Republicans of 鈥渟pewing this fear鈥 at this week鈥檚 Republican National Convention.

鈥淎ll you hear with Donald Trump and all of them talking about fear -- we鈥檙e the ones getting killed. We鈥檙e the ones getting shot. We鈥檙e the ones that were denied to live in certain communities. We鈥檝e been hung. We鈥檝e been shot,鈥 he said.

鈥淎ll you do is keep hearing of fear. It鈥檚 amazing to me, why we keep loving this country, and this country does not love us back. It鈥檚 just really so sad.鈥

Kawhi Leonard, Los Angeles Clippers player

Jersey message: None

Similar to LeBron James, former Raptors player Kawhi Leonard chose not to wear one of the NBA鈥檚 pre-approved messages. Leonard says that he鈥檚 long been invested in supporting the Black community, and he鈥檚 constantly working to educate others.

鈥淲hat鈥檚 happened, what everybody has been seeing on the news, it鈥檚 been like that for me. I鈥檝e been seeing those situations, so it鈥檚 nothing new to me, and I鈥檓 still going to help and educate people as well as my teammates,鈥 he said.

鈥淚t doesn鈥檛 matter if we have a statement on the back of our jersey, it鈥檚 about doing the work.鈥

Norman Powell, Toronto Raptors

Jersey message: Black Lives Matter

Norman Powell wanted to go with the slogan 鈥淎m I Next?鈥 on the back of his jersey, but it wasn鈥檛 among the list of pre-approved messages from the NBA.

Powell expressed frustration at what he called a 鈥渃ookie-cutter鈥 list, but settled on 鈥淏lack Lives Matter.鈥

Following Blake鈥檚 shooting, Powell said it鈥檚 time for police officers to face consequences for their actions.

"They believe they're following the law and they think that's OK," Powell said. "'We did an investigation and we found them not guilty.' And they go home and sleep at night perfectly fine. They live their lives and go to their jobs.

"Until they're on the line for getting fired and having to lose everything, nothing's going to happen."

Masai Ujiri, Toronto Raptors president

As he tried to join his team to celebrate the 2019 NBA Championship victory, Masai Ujiri was shoved by a California sheriff鈥檚 deputy. New body cam footage released last week shows the moments leading up to the shove.

Ujiri said the altercation is clear evidence that there鈥檚 a long way to go in striving toward racial justice.

"I was reminded in that moment that despite all of my hard work and success, there are some people, including those who are supposed to protect us, who will always and only see me as something that is unworthy of respectful engagement. And there's only one indisputable reason why that is the case -- because I am Black,鈥 he said.

"What saddens me the most about this ordeal is that the only reason I am getting the justice I deserve in this moment is because of my success. Because I'm the president of an NBA team, I had access to resources that ensured I could demand and fight for my justice. So many of my brothers and sisters haven't had, don't have, and won't have the same access to resources that assured my justice. And that's why Black Lives Matter."
