Langfield was called up for the Euro 2008 qualifiers against Ukraine and Georgia by manager Alex McLeish after Rangers goalkeeper Allan McGregor withdrew due to a shoulder or elbow injury.
Sunderland and Scotland No1 Craig Gordon said: "He's done well to come back and he's obviously been working hard to get his place back at Aberdeen and put in some good shows since he's been back in the team to get him back to where he is now. It's great for him and I'm sure he'll enjoy it."
