Every case is different, and the individual facts are critical. For a dispositive answer, please consult with an employment lawyer. That said, as a general rule, there is no right to keep working in the same field. If the alternate job is at much lower rate of pay, it might not be considered an adequate substitute. However, if you will be paid fairly comparable to what you had been being paid, then I cannot imagine that you could decline the offer and be able to receive disability (or, for that matter, other benefits, such as unemployment compensation). Again, for advice taking into account your unique situation, consult with an employment lawyer, but if the job you're being offered is a good one, I suspect you would need tot take it.
