Bolton Wanderers signing Tim Ream is still finalising his transfer paperwork.
Ream, whose move was completed last week, is yet to make his Bolton debut and it seems unlikely he will get the chance to do so against Arsenal.
"He is having an appointment at the New York embassy today because after securing his work permit, he now needs to sort out his passport," Owen Coyle said.
"The process starts today and I'm led to believe that it is a 48-hour turnaround, so I think Wednesday might be too tight for him - we'll just have to wait and see."
