What is the test for overturning an evidentiary ruling in the absence of a timely objection?

We do not review evidentiary rulings in the absence of a timely objection unless the accused's substantial rights are affected. United States v. Rogers, 769 F.2d 1418, 1425 (9th Cir.1985), cert. denied, 502 U.S. 973 (1991). Plain error requires a reversal only to prevent a miscarriage of justice or where the error seriously, affects the fairness, integrity, or public reputation of judicial proceedings.
