A Petersburg man was injured in a one-vehicle accident Monday on State Road 56 west of Ireland. The Dubois County Sheriff’s Department says 57-year-old Doug Craig was westbound when his truck drifted across the center line into a ditch. It then hit a large culvert head-on. Craig had to be extricated from the vehicle. He was taken to Jasper Memorial and then airlifted to Saint Mary’s in Evansville.
