(CNN) - The parents of Army Sgt. Bowe Bergdahl addressed their son Sunday, saying they are proud of him.
They spoke with the media one day after he was released after five years in captivity in Afghanistan.
Bob Bergdahl says they haven't spoken directly with their son yet.
"We're talking like this because we haven't talked to Bowe yet, we haven't called him on the phone yet although you all know we have the capability to do that with satellite technology. There's reason for that and that's because Bowe has gone so long that it's going to be difficult to come back," said Bob Bergdahl. "It's just like a diver going deep on a dive and having to stay back up through decompression to get the nitrogen bubbles out of his system. If he comes up too fast it could kill him."
U.S. officials traded five Taliban prisoners being held in Guantanamo for Bowe Bergdahl.
Defense Secretary Chuck Hagel said Sunday that his health was deteriorating and they had to move quickly to save his life.
