In the same comic book as the one where Lynx KO's Black Canary, Black Canary gets out for some revenge against the guy, who is being protected by Lynx. Because she is in the way, Black Canary beats her unconscious. We don't see Lynx getting KO'd but we do see her unconscious body sliding across the table.
