SAN FRANCISCO – The San Francisco 49ers have been riddled with injuries in recent years, and there is a theory about why.

A viral theory, albeit unproven, says the 49ers’ unusually high number of soft tissue and non-contact injuries might be due to electromagnetic fields (EMFs) from a big electrical substation next to their practice fields and Levi’s Stadium in Santa Clara. 

The claim is that being around it for years could weaken tendons and soft tissue, leading to more ACL tears, Achilles injuries, hamstring pulls and similar issues.

Christian McCaffrey, George Kittle, Ricky Pearsall, Brock Purdy, Dre Greenlaw and numerous others have sustained serious injuries over the last couple of years, adding traction to the theory. Greenlaw tore his Achilles in the Super Bowl two years ago, and Kittle ruptured his Achilles last month in the playoffs.

McCaffrey missed all but four games with Achilles tendinitis and a knee injury last season but is not worried one bit.

"Dude, I am not a scientist, and I'm not a doctor. Look, we'll play anywhere. You know, for us, I think that's stuff that a lot of people smarter than me can talk about," McCaffrey told Fox News Digital on radio row.

"All I know is, you know, there's too many variables in football to just say that something like that is the reason for injuries. I mean, you can do everything right and bad things can still happen, so."
