The 26-year-old Ellington, who goes by the same name as his father, has taken a leave of absence from the team.
Wayne Ellington Sr. was found in his car in Philadelphia. He was 57 years old.
“Our players are upset for their friend and teammate. Additionally, ownership and all Lakers employees are also saddened by this tragedy,” said Lakers general manager Mitch Kupchak.
“Those of us who work with and have gotten to know Wayne (junior) have come to know what a wonderful and caring person he is. Our hearts go out to Wayne and his family, as do our thoughts and prayers.”
Ellington is in his first season with the last-place Lakers after spending the last season with Dallas. In five games this season, Ellington is averaging 7.8 points and 3.4 rebounds.
