Is the use of “yours” grammatical in “jeopardize yours and her careers”?

Question

I came across the following sentence:

Another inspector, Douglas E. Peters, testified that even after the F.A.A. manager had been removed, the replacement manager threatened him. The replacement pointed to a photo of Mr. Peters’ family, pointed out that both Mr. Peters and Mr. Peters’ wife had good jobs at the F.A.A., and said, “I’d hate to see you jeopardize yours and her careers” by pursuing ethics complaints against F.A.A. managers. [→]

Is there a trivial error or a simple typo? Or the—so-called— replacement manager had been jeopardized from possessive "her" placed after "yours"?

In other terms, shouldn't it be "your and her" rather than "yours and her"? Or am I wrong?

Answer 1

It could be a typo. It's more likely to be an accurate quote.

"Your and her careers" (or career, if they are similar or linked) is grammatical but awkward.

A better way of expressing that would be her career and yours, from which it's quite easy to see how the error has arisen.
