It is possible that Udoka will be sidelined for the entire season because of the “consensual, intimate relationship,” according to the sports network.
The Athletic independently confirmed the report via sources, who said the relationship was a “violation of organizational policy”.
According to ESPN, Udoka’s job is probably not in permanent danger.
In his first year as head coach last season, Udoka guided the Celtics to the NBA Finals for the first time in 12 years.
A video of Udoka’s girlfriend, actor Nia Long, dancing after the team reached the championship went viral.
The Celtics lost to the Golden State Warriors in six games in the NBA Finals.
The team did not immediately respond to The AU Times’s request for comment.
