(KNZA)--A single-vehicle wreck early Saturday afternoon on a Buchanan County, Missouri road sent a St. Joseph man to the hospital with serious injuries.

The Missouri State Highway Patrol says 56-year-old George Thuston was eastbound on Cook Road, a 1/4 mile east of Riverside Road in St. Joseph, when he lost control of Hummer on the ice covered road.  The vehicle went off the side of the road, struck an embankment and overturned.

Thuston, who was not wearing a seatbelt, was ejected through the sun roof of the vehicle.

He was transported to Mosaic Life Care in St. Joseph.

The wreck was reported shortly after 1:00.
