A worker suffered critical injuries overnight at the Bridgestone tire plant in La Vergne.
The victim became trapped in a tire machine, but other workers were able to extricate him by the time authorities arrived, according to Kathy Tyson, city of La Vergne spokeswoman.
The worker was transported to Vanderbilt Medical Center by LifeFlight.
Officials were able to revive the victim along the way to the hospital, according to Bridgestone spokesman Don Darden.
It's unclear how the person became trapped in the machine.
