Vernon Davis rejects theory linking 49ers injuries to local power station

Former San Francisco 49ers tight end Vernon Davis publically dismissed a theory suggesting electromagnetic fields from a neighboring power substation contribute to player injuries. A social media theory proposed that the Mission Substation, located near the 49ers' Santa Clara headquarters, degrades soft tissue and tendons in players. Davis, who played 10 seasons for the franchise, stated he did not observe such health issues during his tenure. General manager John Lynch confirmed the team commissioned an independent review by an electromagnetic field expert, which concluded the practice environment is safe. The 49ers currently have 11 players on injured reserve as they open the 2026 season against the Los Angeles Rams.
