LA Galaxy released a brief statement on Friday announcing that midfielder Katai and the team had "mutually agreed to part ways," after "strongly condemning" Tea Katai's posts when they became aware of them on Wednesday.
The statement continued: "The LA Galaxy stand with communities of colour, and especially the Black community, in the protests and fight against systemic racism, social inequality, bigotry and violence."
The 29-year-old Katai, who previously played for the Chicago Fire and signed with LA Galaxy in December, has apologised for his wife's social media postings.
