The team added that a decision on Udoka’s future with the Celtics will be made at a later date. His suspension was effective immediately.
According to ESPN, The Athletic and the Boston Globe, Udoka had a consensual relationship with a female member of the team staff.
“I’m sorry I put the team in this difficult situation, and I accept the team’s decision,” Udoka told ESPN in a statement in which he apologized to the players, fans, organization and his family.
CNN has reached out to the Celtics for further comment.
On Friday, Celtics owner Wycliffe “Wyc” Grousbeck and president of basketball operations Brad Stevens spoke to the media to discuss Udoka’s suspension.
Grousbeck explained that the decision to suspend Udoka was made after the organization brought in a “respected law firm to conduct an impartial investigation” after learning of the allegations over the summer.
Grousbeck said he felt the season suspension — which will come with a “significant financial penalty,” according to the owner — is “well warranted and appropriate and supported by substantial research and facts.”
He added: “Ime told me personally in a private conversation, just the general theme was – I would say – acceptance and appreciation for how this has been handled.”
Grousbeck also stated that the players are “very concerned” after conversations with them. “It’s not a welcome development, but they also have, I felt, energy, focus, commitment and drive to achieve really great things this season.”
Stevens was shocked when talking about the impact the news had on women in the organization, saying, “We have a lot of talented women in our organization.
“I thought yesterday was really hard on her. Nobody can control Twitter speculation – rampant bulls**t. We as an organization have a responsibility to make sure we support them now because a lot of people were unfairly dragged.”
Gary Washburn, national basketball writer for the Boston Globe, told John Berman and Brianna Keilar on CNN’s New Day that Udoka could never coach the Celtics again.
“This could have been something that was in his contract,” Washburn said. “You know, ‘You can’t have relationships with members of the organizations, especially those who are under you.’ So, unfortunately, for coach Udoka, he broke those laws, broke those rules and now he’s not out of a job, but he’s as close to a job as he can get.
“He will be suspended for a year and the organization has not promised that he will return in 2023-2024. They said they will review it then, so he can never coach the Boston Celtics again.”
The Celtics begin their season on October 18 against the Philadelphia 76ers at the TD Garden in Boston. NBA training camps open next week with the first preseason games scheduled for a week from Friday.
