Aldon Smith’s cause of death has not been publicly released. His family is donating his brain to Boston University’s CTE Center as attorneys look into whether repeated head trauma may be relevant.

Aldon Smith’s cause of death has not been publicly released. The former San Francisco 49ers linebacker died June 13 at age 36, and his family is donating his brain to Boston University’s CTE Center while attorneys investigate the circumstances of his death.
No. AP and Reuters both reported that no cause of death had been given or released after Smith’s death.
That is the central point for readers searching the cause: there is no confirmed public finding yet. Reports that his brain is being examined for CTE do not mean CTE has been diagnosed, and they do not establish a cause of death.
The 49ers confirmed Smith’s death on June 13 and said the organization was mourning his passing. The team did not announce a cause.
AP reported that Smith died after delivering pizzas to a homeless charity in the San Francisco Bay Area. A friend told the San Francisco Chronicle, according to AP, that Smith was found unresponsive in the front passenger seat of a vehicle after the delivery and was later declared dead at a hospital.
Those details explain why there has been public interest in what happened, but they do not answer the medical question. Until a cause is released by an official source or by the family through a verified statement, any specific claim about how Smith died should be treated as unconfirmed.
Smith’s family has hired attorneys Harry Daniels, Bakari Sellers and Wayne Kendall to investigate his death, according to AP and Reuters. The attorneys said the family has taken steps to send Smith’s brain to Boston, where medical experts will examine it for CTE and other damage linked to years of concussions and trauma.
CTE is chronic traumatic encephalopathy, a degenerative brain disease associated with repeated head impacts. It has been studied in athletes from contact sports, including football players.
The family’s decision is part of a broader effort to understand Smith’s health history and the possible effects of repeated brain trauma. It should not be read as a confirmed diagnosis.
No. CTE has not been confirmed in Smith, and no source checked for this report has said it caused or contributed to his death.
Boston University’s CTE Center says CTE can only be diagnosed after death through postmortem neuropathological analysis. The center also says brain scans, blood tests and spinal fluid tests cannot definitively diagnose CTE during life.
That makes the brain donation potentially important for research and for the family’s search for answers. It does not replace an official cause-of-death determination.
The 49ers selected Smith with the No. 7 overall pick in the 2011 NFL Draft out of Missouri. He made an immediate impact, recording 14 sacks as a rookie and then setting a 49ers single-season franchise record with 19.5 sacks in 2012.


The 49ers said Smith had 44 sacks in 50 regular-season games with San Francisco. NFL.com’s career stats list him with 52.5 sacks in 75 regular-season games across his time with the 49ers, Raiders and Cowboys.
Smith was a first-team All-Pro and a Pro Bowl selection after his 2012 season. His early career made him one of the league’s most disruptive young pass rushers before his time in the NFL was interrupted by suspensions and legal issues.
The next meaningful update would be an official cause and manner of death, a public statement from Smith’s family or attorneys, or any publicly released result from the brain examination.
For now, the accurate answer is limited: Aldon Smith died at 36, his cause of death has not been disclosed, and his family is donating his brain for CTE research. Readers should avoid treating social media claims or unsourced posts as fact unless they are supported by an official statement or a reliable news report.
