After an [article id="1610037"]accident early Sunday morning left Casey Aldridge[/article], the father of [article id="1590596"]Jamie Lynn Spears' child[/article], with mild brain trauma and a "skull fracture around his hairline," sources close to the 19-year-old said on Monday that Aldridge would soon be moved out of ICU at the University of Mississippi Medical Center in Jackson, People.com reported.

"They said it was borderline, whether he needed surgery or not," the source said, "but they've taken some scans and see no further damage."

The source also told People that Spears -- who has a 10-month-old daughter, Maddie Briann, with Aldridge -- is doing OK since her boyfriend was injured in the accident. "Jamie Lynn has been at the hospital, and all indications are that she is holding up well," the family source said.

During the accident, the truck Aldridge was driving flipped on a Louisiana highway, ejecting Aldridge and two of his four passengers. According to People, the passengers, all male, had been coming home from a bachelor party at Aldridge's cousin's house.

One of the other passengers reportedly suffered from broken collarbone, another had a possible hip injury and a third had some mild bruising. Aldridge, 19, has been charged with a misdemeanor count of careless operation of a motor vehicle.

"It's an anomaly that no one was injured more seriously," Louisiana State Police spokesman Mark Dennis told People. "Usually in that kind of accident, you see serious injuries or fatalities."

The family source added, "Only one of them was even wearing a seat belt. There had to be angels all around them."
