San Francisco 49ers GM John Lynch relied on physical evidence to stop a digital rumor that targeted team stability. He addressed a social media claim that reached 22 million people. This false story linked 19 starter injuries to low-frequency waves from a nearby electrical substation.
Lynch hired a scientist independent scientist to conduct precise environmental testing at their practice facility. This logical response provided the 49ers with verified data to protect their reputation.
49ers GM John Lynch confirms 49ers practice site is safe
The San Francisco 49ers experienced a high injury rate during the 2025 season. 19 starters missed significant games including stars Nick Bosa and Fred Warner. These physical losses led to online speculation about the safety of the facility. A viral post claimed that electromagnetic fields were damaging players’ collagen.

An independent investigator measured radiation levels at the Santa Clara facility. The results showed that the frequency levels were 400 times below safety limits. The scientist tested the weight room and the practice fields for hazards. Data confirmed the facility is as safe as a standard commercial gym.
The team invested $9 million in new recovery equipment following the 2025 season. This funding supports advanced sports science to lower future injury risks. The 49ers prioritize player health by using technology based on medical facts. These tools help staff monitor muscle strain and fatigue levels more accurately.
Free-agent signings continued despite viral misinformation on social media. Mike Evans signed a contract for $60.4 million to join the roster. He did not ask about the substation rumors during his contract talks. Other new players signed deals without expressing concerns about the site.
John Lynch called the collagen-melting theories meaningless after receiving the final report. The organization successfully used logic to defeat a story that reached 22 million users. Verified science protected the team from the psychological impact of digital lies.
“We’re in a safe place at work,” Lynch added. “The levels are, I think I read in there, 400 times less than unsafe zones. And so it’s a normal place of work.”
The San Francisco 49ers have launched a major $9 million overhaul of their player wellness and recovery infrastructure for the 2026 season. This initiative directly addresses player concerns highlighted in the NFLPA team report cards, where the training room facilities received a C-minus grade.
A significant portion of the $9 million is being used to expand “hydro areas,” including the addition of new hot and cold tubs for advanced recovery.The team is also hiring three additional physical therapists. General Manager John Lynch noted that modern athletes require more one-on-one attention, and these hires aim to place the 49ers at the “top of the league” in medical staffing.
General upgrades to the rehab and recovery facilities in Santa Clara are designed to reduce the “endless attrition” of injuries that plagued the team during the 2025 season.
Lynch and the 49ers ultimately dismissed the theory as a “big nothing burger,” emphasizing that empirical data proved the workspace was entirely safe for players, coaches, and staff.
