BROOKLYN -- Several players on both the Cleveland Cavaliers and Brooklyn Nets, including LeBron James, Kevin Garnett, Kyrie Irving and Deron Williams, wore black "I Can't Breathe" T-shirts during pregame warm-ups Monday, following in the footsteps of Chicago Bulls guard Derrick Rose who wore the same shirt in a game Saturday to show support for the family of Eric Garner.

"It's not a Cavs thing," James said before the game. "It's a worldly thing."

On several occasions in the past couple weeks, James has spoken out about the deaths of Mike Brown in Ferguson, Missouri, and Tamir Rice in Cleveland. Like Garner, Brown and Rice were both African-American males that died because of a confrontation with a police officer.

"It's just for us to make a [statement] to understand what we're going through as a society," James said when asked about the T-shirt. "I've been quoted over and over about what's going on as far as it's more of a notion to the family, more than anything. Obviously, as a society we have to do better. We have to be better for one another. It doesn't matter what race you are. It's more of a shout out to the family more than anything, because they're the ones that should be getting all the energy and effort."

James told reporters on Sunday he was "looking for" a T-shirt like the one Rose wore. Nets guard Jarrett Jack heard James' comments and supplied the shirts for players on both teams to wear.

"The power of social media," James said.

Before the game, Jack, who played for Cleveland last season, told reporters he offered the T-shirts to members of the Cavs.

"I just heard people's opinion on the topic, and I know [the Cavaliers] are on the road, this is the place where it happened, so if they wanted to be a part of the cause or make a statement without actually necessarily saying any words, I definitely extended the invitation," Jack said.

"Obviously Kyrie was my teammate, so I reached out to him, I heard 'Bron say something about it when Derrick Rose took the stance on it, so I reached out to my people out here, Excel Sports Management [Jack's agency], they was able to make it happen, they made a few shirts for those guys happen over there, so I know us as a team we're gonna go out and try to make a stance and show that we're a team that's not with prejudice. We want to have tolerance for everybody. And I just want to allow those guys to come be a part of it as well as much as we could."
