The 49ers' general manager, John Lynch, refuted a conspiracy theory that an electrical substation's proximity to the team was to blame for injuries. An independent scientist conducted tests on the team's facilities, including the practice fields, the weight room, and even cafeteria. Lynch stated that the levels of electromagnetic waves were 400 times less than an unsafe zone and that the team felt safe. The scientist's identity has not yet been disclosed. The NFL Players Association is following the 49ers’ investigation into the issue.
