An investigation by an independent law firm commissioned by the Boston Celtics found that head coach Ime Udoka used crude language toward a female subordinate before starting his alleged inappropriate workplace relationship with her, according to Adrian Wojnarowski.When the Celtics first learned of the relationship between Udoka and the staff member in July, they were led to believe it was consensual, according to The Athletic.During their Sept. 22 press conference on the matter, neither Celtics co-owner Wyc Grousbeck nor president of basketball operations Brad Stevens would discuss specifics.Udoka's text contained language that was "especially concerning coming from a workplace superior" and will make it difficult for him to ever return as the team's coach, per Wojnarowski's reporting.The 34-year old has only three years of NBA coaching experience and is two years younger than veteran forward Al Horford."
