At the NFL league meetings in Phoenix, John Lynch reported that the organization hired an independent scientist to evaluate the theory. The investigation focused on the substation located next to Levi's Stadium and the 49ers' training facilities. The goal was to determine if the substation was affecting the health of the team's players. Lynch stated that the scientist concluded the situation was safe, with exposure levels 400 times lower than those considered dangerous. The general manager emphasized that the work environment and the gym are safe and healthy.

The theory emerged in January, fueled by a series of posts on X/Twitter by Peter Cowan. Cowan suggested that the substation contributed to injuries to 49ers players, including Brock Purdy, Nick Bosa, and Fred Warner. He argued that low-frequency electromagnetic fields could degrade collagen and weaken tendons, causing soft tissue damage. Cowan highlighted that the injuries suffered by 49ers players were tendon and ligament tears.

Fullback Kyle Juszczyk, in January, expressed his desire for the team to investigate the substation. Tight end George Kittle also shared the player's concerns. The players' stance reflected caution about the possibility of external factors influencing their health and performance. The investigation became a priority for the team, seeking answers and ensuring the safety of its players.

Jerrold Bushberg, a radiology professor at UC Davis, stated that there was no firm evidence linking low-level exposure to effects on human health. Bushberg, who chairs the board of directors for the National Council on Radiation Protection and Measurements, explained that the supposed mechanisms have not been proven and that many experiments are contradictory. Furthermore, he noted that the exposures in some experiments are not specifically related to 50 or 60 hertz magnetic fields, or are at much higher levels than those experienced on the training field.

The conclusion of the scientific study was clear: the electrical substation was not the cause of the players' injuries. The results reassured the organization and the players, who can now focus on their performance on the field. General Manager John Lynch emphasized the importance of safety and health in the workplace.

The team's quick response and transparency in addressing this concern demonstrate its commitment to the well-being of the players. The investigation, although it found no connection, served to dispel doubts and strengthen confidence in the team's practices. The case highlights the importance of scientific investigation and verification of information before drawing conclusions based on speculation.
