ORDERED that the order is affirmed insofar as appealed from, with costs.
The evidence submitted by the respondent, Dr. George Delshad, which included affidavits of two medical experts, was sufficient to establish his entitlement to summary judgment as a matter of law. The burden then shifted to the plaintiff to present competent evidence sufficient to raise a triable issue of fact (see, Alvarez v. Prospect Hosp., 68 N.Y.2d 320). The Supreme Court properly determined that the report by the plaintiff's medical expert, which was neither sworn to nor affirmed to be true under the penalties of perjury, did not constitute competent evidence sufficient to defeat the respondent's motion (see, Mezentseff v. Ming Yat Lau, 284 A.D.2d 379; Baron v. Murray, 268 A.D.2d 495; Moore v. Tappen, 242 A.D.2d 526; CPLR 2106). Even if the report by the plaintiff's medical expert constituted competent evidence, it was too conclusory to raise a triable issue of fact and failed to rebut the opinion of the respondent's medical expert that the plaintiff's alleged nerve damage could not have been caused by the surgery performed by the respondent (see, Rodney v. North Shore Univ. Hosp., 286 A.D.2d 382; Fhima v. Maimonides Med. Ctr., 269 A.D.2d 559).
