Former 49ers defensive star Aldon Smith dies at age 36, team announces
Aldon Smith, who put up one of the greatest rookie seasons by a defender in NFL history when he debuted with the San Francisco 49ers as an elite pash rusher in 2011 but whose career faltered among legal trouble and suspensions, died Saturday, the team announced. He was 36.
A cause of death was not immediately disclosed, though the 49ers in a statement Saturday afternoon called his passing “sudden and tragic.”
“We are devastated by the sudden and tragic passing of Aldon Smith. Aldon’s undeniable talent and sheer dominance on the field were on display from the moment he joined our organization, having recorded one of the best rookie seasons the National Football League has seen,” the team’s statement said.
“Beyond his excellence as a player, Aldon will be remembered for his infectious smile that lit up every room he walked into. Our entire organization sends its deepest condolences to the Smith family and all who knew and loved Aldon.”
The 49ers drafted Smith seventh overall in the 2011 NFL draft out of the University of Missouri. He recorded a team-high 14 sacks in 2011 and 19.5 in 2012. The latter remains the 49ers franchise record, and 33.5 sacks remains the record for any player in their first two NFL seasons.
Smith played a key role in the 49ers’ dominant defense in the early 2010s under head coach Jim Harbaugh, which earned San Francisco an NFC championship and appearance in Super Bowl XLVII, which the 49ers lost to the Baltimore Ravens. Smith and linebacker teammates NaVorro Bowman, Ahmad Brooks and Patrick Willis were all named to the 2012 All-Pro team.
Born in Mississippi before starring at Missouri, Smith’s NFL career derailed in 2013. That September, he was arrested on suspicion of driving under the influence and possession of marijuana following a vehicle crash in San Jose. Smith voluntarily entered a rehab facility, returning to the 49ers late in the season before being suspended by the NFL for nine games in 2014.
After an August 2015 arrest on suspicion of DUI and hit-and-run, the 49ers released him. The then-Oakland Raiders signed Smith the following month. After nine games with the Raiders, the NFL suspended Smith again, this time for one year, in connection with the August 2015 vehicle incident.
Suspended throughout the entire 2016 and 2017 seasons, the Raiders ultimately released Smith in March 2018 following an arrest on suspicion of domestic violence.
Smith in 2020 successfully applied for reinstatement to the NFL from indefinite suspension and signed a one-year contract with the Dallas Cowboys. He started all 16 games with Dallas that season, tallying five sacks and a defensive touchdown.
The Seattle Seahawks signed Smith to a one-year contract in April 2021; days later, the St. Bernard Parish Sheriff’s Office in Louisiana issued an arrest warrant for Smith on a second-degree battery charge. The Seahawks released him before the start of the 2021 season.
Smith on a 2023 podcast appearance stated that he had retired from football; at the time, he had been recently released from jail after serving six months for a 2021 DUI incident.
Smith helped catalyze the 49ers’ historic turnaround during his rookie season in 2011 thanks to his ability to disrupt quarterbacks. The defense improved from 13th to fourth in opponents’ yardage, while Smith led the team with 14 sacks, nearly double that of Justin Smith’s 7.5, who was second.
San Francisco went from 6-10 in 2010 to 13-3 and made the first of three straight appearances in the NFC championship game, a Super Bowl appearance after the 2012 season. His first two seasons accounted for 64% of his sacks by the time his playing career ended in 2020.
