Doctors at the University of Mississippi Medical Center in Jackson, Miss., said they plan on moving Casey out of ICU as soon as Monday, according to People magazine.
"They said it was borderline whether he needed surgery or not," says a source close to the family, "but they've taken some scans and see no further damage."
The accident occurred at 1:30AM Sunday. Casey was driving his Ford F-250 pickup truck from his cousin's bachelor party towards Lake Bruin in Parish, Louisiana.
Three out of five passengers, including Casey, were ejected from the car during the accident, so they're all lucky to be alive. Police have already ruled out drugs and alcohol.
As for his baby mama, Jamie Lynn, she's said to be "holding up well." She was spotted at the airport Monday afternoon with her mother and daughter, but she was with Casey in the ambulance and spent most of her Sunday by Casey's side.
