A debunked conspiracy theory with no basis in reality linking a power substation to injuries to the San Francisco 49ers has made its way up to general manager John Lynch.

The theory is that low-frequency radiation from an electrical substation near Levi’s Stadium and the 49ers practice fields might have contributed to the team’s significant number of injuries. Experts in radiation told SFGATE last week there’s no proof to back up that theory, with one expert going so far as to say, “It’s just not possible.”

The San Francisco 49ers have a player NFL teams may covet this offseason, but the 49ers may not be open for business.

President of Football Operations John Lynch said Wednesday that Brandon Aiyuk "has [likely] played his last snap" with the 49ers.

As David Lombari of The SF Standard shared on Twitter/x, 49ers GM John Lynch revealed his feelings on bringing Jennings back this offseason. Fortunately for any fans who want to re-sign Jennings, Lynch seems more than open to the idea.

It's safe to say Lynch, 54, did not foresee all the injuries that piled up this season — but the wins piled up as well.

After some strong play in relief of Brock Purdy in 2025, Mac Jones' season-ending social media post had 49ers fans thinking about the future.

The 49ers overachieved in 2025, but pressure will continue to mount on Kyle Shanahan and John Lynch in their 10th seasons with the team in 2026.
