Out for a jog...

Amazing story, excerpted from WSLS NewsChannel 10 (emphasis added)

Since Kevin's leg was still attached to the tractor, there was no way to get him to the hospital fast. Battalion Chief Dustin Campbell made the call to amputate Kevin's leg right there in the field, a procedure they'd never done before.

Battalion Chief: Dustin Campbell: We were discussing who was going to have to amputate when an ER physician out for a jog popped in and said, hi I'm a doctor can I help? And basically he was elected.
