The San Francisco 49ers‘ defensive front will have a different look in 2026 following a decision that has resonated far beyond the locker room.
Veteran defensive end Bryce Huff announced his retirement from professional football, choosing to walk away from a contract that would have paid him $17 million this upcoming season.
While the 27-year-old is coming off a productive campaign in which he recorded four sacks and 46 quarterback pressures for San Francisco, he informed the league that his focus has shifted from rushing quarterbacks to solving a critical global safety crisis.

Huff is officially launching Naberstone, a company co-founded with his brother, Jordan Huff, dedicated to developing specialized infrastructure for the suppression and containment of lithium-ion battery fires.
The decision marks a pivot that is virtually unprecedented for a player in his athletic prime. Huff, who entered the NFL as an undrafted free agent in 2020, rose to prominence during a standout four-year tenure with the New York Jets before signing a historic $51.1 million contract with the Philadelphia Eagles in 2024.
Although he earned a Super Bowl LIX ring with Philadelphia, his path was complicated by a significant wrist injury that sidelined him for several games and a defensive scheme that he publicly admitted was a poor fit.
These professional hurdles, combined with the perspective gained during his rehabilitation, ultimately sparked the realization that his impact on the world could extend beyond the boundaries of a football field.

The founding of Naberstone represents a “full-tilt” commitment to public safety as battery technology continues to scale across the globe.
Huff explained that modern suppression systems are often inadequate for the unique thermal runaway risks associated with lithium-ion batteries, a problem he intends to solve through proprietary suppression and detection technology.
By retiring now, Huff aims to lead his company with the same discipline and perseverance he applied to his journey from an undrafted rookie to one of the league’s most efficient pass-rush specialists.
“It’s time for the next chapter of my life,” he said.
“I’m building a company called Naberstone. Lithium-ion batteries power the modern world but they carry a fire risk that current suppression technology was never designed to solve. We’re building safety infrastructure specifically for that problem,” Huff stated in his announcement.
“I can’t ask the people who believe in this mission to go all in if I’m not willing to do the same. Football gave me everything and now it’s time for me to give everything to something new.”
