Aldon Smith, the former All-Pro edge rusher who set a single-season franchise record for the San Francisco 49ers, died on Saturday at age 36. Authorities have not yet disclosed a cause of death for the former first-round NFL draft pick, who most recently played for the Dallas Cowboys in 2020.
Final Moments and Emergency Response in Los Gatos
The discovery of Smith’s death occurred at a private residence in Los Gatos. Amir Shirazi, a businessman and longtime friend of the former linebacker, reported finding Smith unresponsive in the passenger seat of a pickup truck Saturday morning. According to the San Francisco Chronicle, Shirazi initially suspected a medical emergency, such as a seizure or heart attack, and contacted 911 while attempting to administer CPR with the help of former 49ers running back Anthony Dixon.
Emergency personnel transported Smith to Good Samaritan Hospital in San Jose, where he was pronounced dead less than an hour later. The Santa Clara County chief medical examiner is currently investigating the cause and manner of death. Standard protocol for such investigations involves toxicology screenings and a thorough review of medical history, a process that can take several weeks before a final determination is released to the public. Shirazi noted that Smith had recently returned to the Bay Area from Texas, where he had been living, and was navigating financial instability while waiting for his NFL pension to begin.
An Explosive NFL Career and 49ers Franchise Records
Selected seventh overall in the 2011 NFL Draft, Smith emerged as one of the league’s most disruptive defensive talents. The Athletic reports that Smith recorded 14.0 sacks during his rookie campaign, narrowly missing the NFL rookie record held by Jevon Kearse. He followed that performance in 2012 with 19.5 sacks, a single-season franchise record that stands to this day. During those initial years, Smith served as a cornerstone for a San Francisco defense that reached three consecutive NFC Championship Games and a Super Bowl appearance in the 2012 season.

Smith’s emergence was a catalyst for the 49ers’ defensive dominance under head coach Jim Harbaugh. His ability to bend the edge and disrupt opposing quarterbacks made him a central figure in the team’s schemes, often drawing double teams that opened opportunities for teammates like Justin Smith and Patrick Willis.
Vic Fangio, who served as the 49ers’ defensive coordinator during Smith’s rookie season, reflected on the player’s early trajectory and professional development.
“He was a really fun guy to coach — challenging at times — but fun to coach in that you could see him getting better every day,” Fangio said. “… The future was just as bright as could be for him. Then the off-field stuff derailed his career there.”

Off-Field Challenges and League Suspensions
Smith’s career was frequently interrupted by personal and legal challenges. According to reporting from the Dallas Cowboys’ official site, Smith was suspended for multiple seasons due to violations of the NFL’s Policy and Program for Substances of Abuse. The league’s disciplinary process for substance abuse is structured in stages, ranging from clinical evaluations and counseling to multi-game and multi-season suspensions for repeat violations. Smith’s history of suspensions significantly altered his career trajectory, preventing him from building on his record-setting early pace.
His legal history included multiple arrests for driving under the influence and a domestic violence case, leading to his release from the 49ers in 2015 following a hit-and-run incident. After playing for the then-Oakland Raiders in 2015, Smith remained out of the league for four seasons before returning for a final stint with the Cowboys in 2020. During that season, he appeared in all 16 games, recording five sacks and scoring a touchdown on a 78-yard fumble return against the New York Giants. Following his time in Dallas, he signed with the Seattle Seahawks in 2021 but was waived before the season began. In 2023, Smith served a six-month prison sentence following a guilty plea for felony DUI.
Broader Context of NFL Life and Transition
The death of Smith has prompted reflection on the challenges professional athletes face after leaving the league. The NFL provides various resources, including the NFL Player Care Foundation and the NFL Legend Community, which are designed to assist former players with physical, emotional, and financial transitions. These programs are often highlighted by the league when discussing the well-being of its alumni, though the personal nature of individual struggles often complicates the efficacy of these support systems.

Community Impact and Legacy
Despite his struggles, those close to him emphasized his character outside of football. Shirazi detailed that on his final day, Smith had participated in an effort to deliver pizzas to a homeless charity. “My impression was that this is a young man that wanted to help the homeless, which was great,” Shirazi told the Chronicle. “When the 49ers and people like that want to help the community, that’s everything.”
The 49ers organization issued a formal statement expressing their condolences, highlighting Smith’s “undeniable talent” and the impact he had on the franchise during his tenure. As of Sunday, no funeral arrangements or public memorial services have been announced by the Smith family. The team’s statement serves as a reminder of the complex relationship between the franchise and the player, acknowledging his professional contributions while mourning his passing.
