The Pentagon says Army Sergeant Bowe Bergdahl, who was released after five years as a prisoner of the Taliban in Afghanistan, is likely to set foot on U.S. soil again in San Antonio, 1200 WOAI news reports.

A Pentagon official, debriefing reporters off the record, says the plan is for Bergdahl to remain at the U.S. Military Medical Hospital in Landsthul Germany, where he arrived this morning, for as long as necessary to stabilize what the official called a 'deteriorating medical condition.'

As soon as Bergdahl is fit enough to make the trip, it is expected that he will then be flown to San Antonio Military Medical Center, where he will undergo additional treatment.

It is not known whether Bergdahl will be reunited with his parents here or in Germany.

The Pentagon official stressed that the situation is fluid and plans may change.

Bergdahl's father told CNN that, after speaking with his son by phone from Afghanistan on Saturday, he was having trouble speaking English, after five years as the captive of Pashtun tribesmen in Afghanistan.
