The Ultimate Fighting Championship is selling rainbow-colored shirts with the slogan "We Are All Fighters," with all proceeds going to the LGBTQ Center in Las Vegas. The big UFC 200 fight card is being held Saturday in Las Vegas.

"Just as it takes courage to step into the Octagon, it takes courage to stand for what you believe in — and we're proud to stand with members of the LGBTQ community in their fight for equality," said Ike Lawrence Epstein, UFC Senior Executive Vice President and Chief Operating Officer. "As friends and allies of the LGBTQ community, our hope is to raise awareness and help support community groups like the LGBTQ Center that directly impact LGBTQ individuals."

Some UFC athletes have worn the shirts this week. They can be purchased at T-Mobile Plaza or at UFC Fan Expo through Sunday. The shirts are expected to be sold online at a later date.

The "We Are All Fighters" initiative is "designed to make a meaningful impact in communities where UFC events are held by supporting organizations that help people overcome adversity, achieve equality, or provide a public service," the UFC said in a statement.

There will be an open lesbian fighter on Saturday's main fight card. Amanda Nunes, who is openly gay, will fight Miesha Tate for the women's bantamweight title.
