GRAND JUNCTION, Colo. (KKCO) - A Grand Junction man injured in an oil rig accident is still in a burn unit at a Utah Hospital.

Jeremiah Thurston is listed in critical but stable condition.

Thurston and another Grand Junction man were injured in a rig explosion in the Bookcliffs in Grand County October 22.

Sheriff's officials say 25-year-old Thurston was on a drill rig cleaning out a gas well when fumes from a flow-bank tank drifted toward the rig motor causing it to rev. The two men were walking toward the motor to turn it off when the fumes ignited around them.
