San Francisco 49ers general manager John Lynch did his best to shut down the buzz around the theory that an electrical substation near Levi’s Stadium could be the catalyst for the spate of injuries the team has suffered over the last few years.
The theory popped up on social media during the 2025 season, though the 49ers have played at Levi’s Stadium since 2014 and used the practice facility that is also near the substation since 1989.

Niners star George Kittle said in February he didn’t believe the rumors were true, but also wanted a definitive answer.
Lynch provided one Sunday as NFL owners began to meet in Phoenix, Arizona. He said the organization had a scientist come to the facility to see if there was anything awry.
“It basically was a big nothing burger,” Lynch told reporters, via ESPN. “We’re in a safe place of work…. It’s a normal place of work. It’s a normal gym. We are safe, we’re healthy, and we feel really good about that.

“That was important to us, not just to turn a blind eye, but to look into it because it’s our players’ wellness. It’s not only our players’ wellness, it’s coaches, it’s staff, all that. And it’s encouraging.”
According to the 49ers, the scientist learned that players and staff were being exposed to an electromagnetic environment similar to that of a gym or average workplace.
Still, the injury bug is something the 49ers have to figure out as the seasons go on.

For now, it appears the substation theory has been shut down.
