oooopps
The 319th squadron is a holding squadron for individuals who will either heal, or be discharged for medical/administrative reasons. Depending on his condition (you didn't specify what was going on with him) will depend on how long it may take for him to be discharged. He will undergo exams to determine if the condition was caused by boot camp or if it was pre-existing. Depending on how long he has been there, he may still have the "zero-week" jitters. Don't worry though, they aren't beating him. He actually, most likely, has got it easier than his previous squadron (less inspections, a little more free time, etc.) unless things have changed recently. He is probably just distressed about the situation more than anything.
It could take less than a week or as much as several weeks. The military fluctuates on promptness from time to time. He should get home to you in one piece, though.
Best regards-
