Long and Udoka share a 10-year-old son and have been engaged since 2015.
CNN has reached out to representatives of Long for comment.
She is beloved, especially by the Black community, as she has starred in such classic films as “Love Jones” and “Boyz N The Hood.”
“I want to apologize to our players, fans, the entire Celtics organization, and my family for letting them down,” Udoka said in a statement to ESPN. “I am sorry for putting the team in this difficult situation, and I accept the team’s decision. Out of respect for everyone involved, I will have no further comment.”
“He’s one of the most disciplined people I know. He’s worked really hard for this and now he’s got to just get to work with his players and do what he does best,” she said at the time. “So, it’s an exciting time for our family to be able to sit in the stands.”
