First, your husband can apply for an Individual Tax Identification Number (ITIN) by submitting a Form W-7 with his return (or with joint return if you want to go that route).
OR
You can re-file your MFS return by mail and print where his SSN goes the words "non-resident alien".
I recommend filing jointly. For one thing, once he files such a return, he has taken the first step to being recognized as a resident alien who is married to a U.S. citizen.
