Boston Celtics star Kyrie Irving was given the Lakota name Little Mountain by the Standing Rock Sioux tribe Thursday.

Wearing a traditional shirt with ribbons, Irving stood on a buffalo skin and was prayed over by a tribe elder, Vernon Iron Horse. As a drum group played and chanted, Irving was wrapped in a blanket, had an eagle feather tied into his hair along with a medicine ball made of porcupine quills, and had a beaded medallion placed over his head as his name was revealed to him.

Irving’s older sister, Asia, was also part of the ceremony and was given the Lakota name Buffalo Woman.

The tribe and Irving have been working since April to put together a time for him to come and take part in a naming ceremony, which is sacred in Native American culture. Pretty neat honor.
