6:47 PM PT -- The Celtics have just suspended Ime Udoka for the entire 2022-23 season ... saying the coach violated team policies.
Udoka apologized to his players, fans and family shortly after the announcement was made.
The Celtics added that Udoka's suspension could last longer than this year -- saying in a statement, "A decision about his future with the Celtics beyond this season will be made at a later date."
Udoka will begin serving his ban immediately, the team said.
Boston Celtics head coach Ime Udoka reportedly had an inappropriate relationship with a female staffer ... and he's now facing a suspension over it all.
ESPN's Adrian Wojnarowski reported Wednesday night the 45-year-old was found to have had a "consensual intimate relationship" with a woman who has a role on the Celtics' staff -- a violation of Boston's franchise guidelines.
As a result, according to Woj, Udoka is facing a ban from the team that could be "significant." Udoka's job, however, is not believed to be on the line.
Further details regarding the allegations were not disclosed. Udoka and the Celtics have yet to address the report.
Udoka -- who took the Celtics job in 2021 and led the team to an NBA Finals appearance in his first year as head man -- has been in a relationship with actress Nia Long since 2010.
