The striker joined Galatasaray on a season-long loan this summer, but Albion retained a recall option.
Potter said: "I don't think we are at that point where we can guarantee that to anybody, I don't think that is healthy "I understand players sometimes have to look after themselves. They have got careers and families.
"We have a recall in January and we will monitor his progress.
"Sometimes players just need to play regularly and kick-start again."
