The San Francisco 49ers opened another season with injury problems already piling up, placing 11 players on injured reserve and two more on the PUP list as the club again finds itself under a spotlight it did not ask for. The latest wave of absences has pushed the long-running 49ers substation theory back into circulation, even as the team heads into the season with more questions than healthy bodies.
That search has a simple trigger: the 49ers practice right next to Levi's Stadium in Santa Clara, California, and the facility sits extremely close to the Silicon Valley Power Mission Substation. The practice building, the stadium and the electric substation have been basically on the same block for over a decade, and the location has become a frequent talking point among players who have watched the team deal with a steady run of soft-tissue injuries.
Isaac Guerendo was among the players still working back from injuries he had when training camp opened, along with Mykell Williams. Their status fit the larger picture: a roster already thinned by availability problems before the first week of the season had even settled in. In that setting, it was enough for old chatter to start moving again, because the substation theory has always offered an easy explanation for a hard problem.
The theory surfaced publicly in January, when Peter Cowan suggested that low-frequency electromagnetic fields from the substation could lead to soft-tissue injuries for football players. Cowan framed it as a real-world case study, but the idea has never been backed by proven scientific support. Experts in the field have dismissed it as nothing more than a talking point, and there is no established evidence that living or working near an electric substation makes people more vulnerable to injury.
That gap between suspicion and proof is exactly why the theory keeps hanging around. The 49ers have had enough injury trouble to keep the speculation alive, and Jon Feliciano’s joke about players laughing around the electrical substation showed how deeply the idea has seeped into the team’s own conversation. Still, the numbers on the opening roster matter more than the folklore: 11 players on injured reserve and two on the PUP list is not a rumor, and it leaves San Francisco trying to start a season while already short-handed.
What comes next is less about the substation than the season itself. If the 49ers can stay healthier, the theory will fade again. If the injuries keep coming, the old explanation will keep finding new listeners.
