Scotland assistant McGhee added Hull player to that list.
He said: "George Boyd has gone home. He has had some sort of ankle injury I think.
"We know about James and Graham, they are a big loss, both of them, but we brought in other and we are getting on with it.
"Quite a few of them didn't train today but we are expecting a full complement tomorrow."
