Autopsy report says Grizzlies forward Brandon Clarke died from effects of heroin and cocaine

Memphis Grizzlies forward Brandon Clarke died in May from the effects of heroin and cocaine, according to information attributed to an autopsy and the coroner’s report. Authorities said both drugs were found in his system, and the medical findings were later provided through official channels referenced by the report.

Clarke, a veteran presence in Memphis’ frontcourt, was 28. The reported cause of death frames the investigation around toxicology results, rather than a single-drug issue, indicating that multiple substances were present and that the combination contributed to the fatal outcome.

The determination described in the coroner’s materials matters because it helps close the gap between the public timeline and the medical facts. In most high-profile sports deaths, the question immediately becomes what was found and what role it played, and this type of report typically becomes the clearest official answer available to families, teammates, and the league.

For the Grizzlies, the report arrives after a difficult period for the organization and its players. While the team’s on-court work has its own rhythm, sudden absences change how coaches manage minutes and roster planning. In practical terms, the team would also have to carry the emotional weight of the loss into the grind of the season.

Across the NBA, the league and teams operate with an ongoing emphasis on player health and safety, including education about substance use and resources for treatment. When an autopsy points to illicit drugs as a contributing factor, it renews focus on prevention, access to help, and how teams support players beyond training and conditioning.

The toxicology finding also sets a boundary on speculation. Instead of debating what happened in the hours or days leading up to Clarke’s death, the official framing emphasizes what the coroner found and how those substances affected the body. Investigators typically still maintain the right to pursue broader questions, but the core medical cause becomes part of the public record.

What to watch next is whether authorities provide any additional clarification about the timeline, circumstances, or any ongoing investigative steps. For basketball observers, the short-term reality is that Memphis must continue to adjust without a player who had been part of the team’s rotation, while the broader league community continues to process a death that has now been medically characterized in an official report.
