"The physician started to perform the operation, but the patient was not yet completely under anesthesia."
The question asked to identify the incorrect word or phrase in this sentence, however, there is nothing that really strikes me as "wrong". I'm not exactly sure what grammar rule I'm overlooking here.

I don't see any errors, either — well, unless these words —> "yet completely" <— are considered unnecessary since "not" is already there.
