"Since both Barker and [Adam "DJ AM"] Goldstein are in overall good health and didn't suffer from any other crash-related complications, a full recovery is expected," said Dr. Fred Mullins at a press conference on Sunday morning.
In a separate press conference on Sunday, National Transportation Safety Board member Debbie Hersman said that the plane's crew members thought a tire burst as they started down the runway.
Hersman said the plane's cockpit voice recorder had been recovered from the wreckage. On it, pilots of the Learjet told air traffic controllers they heard a tire burst and were going to abort takeoff.
She added that the cause of the crash is being investigated.
Earlier in the day, Travis and AM's doctor detailed the pair's injuries and said, "Anybody who can survive a plane crash is pretty lucky."
Dr. Mullins said Barker was burned on his torso and AM was burned on his hands and part of his head. Both suffer second- and third-degree burns, and remain in critical but stable condition at the Joseph Still Burn Center in Augusta, Ga.
He said that recovery from such burns can take up to one year but expects theirs to be "much sooner than that" since they had no other injuries.
At the press conference, Mullins relayed a message from their families: "The families wish to thank fans from all over the world for their prayers and concern. Deepest sympathy is expressed to the loved ones of those who perished in the crash. As the two recuperate and mourn this loss, privacy for them, their families and friends is requested at this time."
