IRLJ 3.1(b) reads (in part):
If the prosecuting authority, without reasonable excuse or justification, fails to provide the citing officer's sworn statement, the statement shall be suppressed.
IMHO the fact that your discovery request was not received until 13 days before the hearing, does not constitute a "reasonable excuse" for not providing the officer's sworn statement AT ALL. If the officer's statement is not forthcoming, I'd move for dismissal based on the sentence I've quoted above.

Good luck,
