Overview
- At a Super Bowl week news conference Tuesday, NFLPA leaders said they are monitoring electromagnetic field questions at Levi's Stadium after player inquiries, with president Jalen Reeves-Maybin calling for more data.
- The 49ers say they are contacting outside experts to review the claim and will assess objective measurements before drawing conclusions, according to general manager John Lynch.
- Running back Christian McCaffrey said EMF and related exposures are "not nothing" and that he is researching potential effects without endorsing drastic claims.
- NFL chief medical officer Allen Sills has publicly disputed a causal link between the substation and injuries, and experts cited in coverage say current evidence does not support the theory.
- Team CEO Jed York noted the adjacent Silicon Valley Power substation has been in place for decades near the practice site, and no independently validated field readings or peer-reviewed findings have been released.
