Accept / Defer from wait list for Fellowship

I recently found out that I was awarded a Fulbright Research Grant. At the time I was already accepted to a medical school and they agreed to defer my enrollment. I was and am still waitlisted for other schools I'd like to attend. Should I mention this to schools where I'm waitlisted? At this point in time, would any school have interest in admitting an applicant they know will defer? Even if it's for a Fulbright research scholarship?
