Former NFL player Aldon Smith dies at 36, and his family says it is donating his brain to the Boston University CTE Center to examine whether chronic traumatic encephalopathy (CTE) may have contributed to his death. Multiple outlets report that the cause of death has not been publicly determined. The family’s decision follows ongoing questions about the long-term effects of repetitive brain injuries associated with football. The Guardian notes Smith died suddenly on Saturday after delivering pizzas for a homeless charity in the San Francisco Bay area, and no cause of death was immediately provided. The Athletic and other reports describe that Smith’s family has hired attorneys to investigate the circumstances of his death. Fox News and The Independent similarly focus on the planned donation for expert examination. New York Post and Yahoo Sports add that the brain will be sent for medical review specifically aimed at checking for signs of CTE. Overall, sources agree the donation is intended to support research into repeated head trauma while the family continues legal inquiries as the death remains under investigation.
