The death of Memphis Grizzlies forward Brandon Clarke has been ruled accidental, with the Los Angeles County Medical Examiner stating that it resulted from “the effects of heroin and cocaine.”

The Medical Examiner’s full report will be released at a later date, according to a statement from the office.

Clarke was found unresponsive in his bedroom on May 11 and was pronounced dead at the scene by paramedics. A deputy medical examiner conducted an examination the following day before the cause and manner of his death were officially certified on Friday.

NBA commissioner Adam Silver expressed his condolences following Clarke’s death in May, describing him as a valued member of the Memphis Grizzlies and a respected leader within the team.

“As one of the longest-tenured members of the Grizzlies, Brandon was a beloved teammate and leader who played the game with enormous passion and grit,” Silver said. He also extended his sympathies to Clarke’s family, friends and the Grizzlies organisation.

Clarke was selected 21st overall by the Oklahoma City Thunder in the 2019 NBA Draft before being traded to Memphis just days later.

During his seven seasons with the Grizzlies, Clarke played 309 games, averaging 10.2 points, 5.5 rebounds and 1.3 assists per contest.

Clarke was 29 years old and held both American and Canadian citizenship. He was born to a Canadian mother and a Jamaican father.
