The Chicago Sports Alliance, which includes the NFL's Bears, NBA's Bulls, NHL's Blackhawks and MLB's Cubs and White Sox, made a commitment of $300,000 to find "evidence-based solutions to gun violence" after recent mass shootings in Texas and Buffalo.
Here's the teams' full statement:
On Tuesday, 19 students and two teachers were killed at Robb Elementary School in Uvalde, Texas.
That tragedy occurred less than two weeks after a racist mass shooting at a Buffalo grocery store killed 10 people.
Both shootings were carried out by gunmen who used high-powered assault rifles.
Golden State Warriors head coach Steve Kerr delivered one of the most impassioned speeches about his desire for improved gun-control measures on Tuesday:
It's one snippet of the effort made by sports teams and players since the shootings.
The New York Yankees and Tampa Bay Rays used their social-media accounts to raise awareness about gun violence rather than providing game coverage during Thursday's contest.
Minnesota Vikings cornerback Kris Boyd, a Texas native, started a GoFundMe fundraiser to benefit the families whose children were killed in Uvalde.
"These are children, man. ... Try to put that in your mind," Boyd said. "I saw something on Twitter that said they had to identify these kids by their backpacks. I was devastated. I cried."
Donations from the Chicago sports franchises will benefit two organizations.
The Robb School Memorial Fund was set up to help families impacted by the tragedy.
The Sandy Hook Promise Foundation was established after a 2012 school shooting in Connecticut where 20 children and six staff members were killed. It aims to "honor all victims of gun violence by turning our tragedy into a moment of transformation."
Chicago's teams said they are "committed to making a difference through our resources in this gun violence epidemic."
