Investigation found Boston Celtics coach Ime Udoka

Ime Udoka's use of coarse language in his conversation with a female subordinate prior to the beginning of an improper working relationship with

the woman was discovered by an independent law firm investigation, which played a significant role in the severity of his one-year suspension, sources told ESPN.

These investigative results, which detailed Udoka's use of language that was particularly alarming coming from a superior,

add to what is likely to be a challenging road to his reinstatement as Celtics coach in 2023, sources told ESPN.

The legal firm's research, which was commissioned by the Celtics and finished early,

identified the power dynamic connected to a superior's unlawful relationship with a team member as the main finding and policy violation.
