The celebration will include a naming ceremony, performances, and community feed at the Prairie Knights Pavilion, a casino in Fort Yates, North Dakota.
Irving's late mother, Elizabeth Ann Larson, was adopted out of the White Mountain family of the tribe and his grandparents and great-grandparents were citizen of the tribe, according to the tribe's release.
After undergoing season-ending knee surgery, Irving posted a message on Instagram that featured the Standing Rock tattoo he has on the back of his neck and ended the hashtag, "#StandingRockSiouxTribe"
The hardest thing to do sometimes is accept the uncontrollable things life throws at you. You try consistently to learn, grow, and prepare everyday to equip your mind, body, and spirit with tools to deal with some of those things, but I feel when those moments arise they all give you a sense of unfulfillment, simply because it puts some of your professional journey and goals on a brief hold. It's simply a test of your perseverance and Will, to be present, even in the wake of what's going on. In this case, finding out I have an infection in my knee is definitely a moment that I now accept and move past without holding on to the all the what ifs, proving the nay-Sayers completely f***ing wrong, and accomplishing the goals I've set out for the team and myself. This season was only a snapshot of what's to come from me. Trust Me. "The journey back to the top of Mt. Everest continues." #StandingRockSiouxTribe Let's go Celtics!! Celtics fans, I look forward to hearing how loud it gets in the TD Garden during the playoffs and experiencing how intense the environment gets. Thank you all!
In June, Irving's released the "N7" version of his Kyrie 4 basketball shoes which featured a Standing Rock seal on the heels of the shoes.
In its release about Irving's ceremony, the tribe noted, "Kyrie has long known about his heritage and connection to the Standing Rock Sioux Tribe and was an active supporter of the NoDAPL movement.
"We could not be more excited, he has made us all very proud," chairman Mike Faith said via the tribe's release. "To know that he has not forgotten his roots and is taking the time before he starts his basketball season to visit the People, his People, shows that Kyrie has great character and pride in his heritage."
