Can I use "who" after a possessive?

Example: I punched the man's nose, who cried in pain.

I just feel like it's refering to the nose instead of the man, even though the meaning is clear.

Can I use “who” after a possessive? Example: I punched the man's nose, who cried in pain.

The Answer is yes However in the example shown you cannot. It would have to be a relatively unusual/special sentence for you to be able to use who after a possessive.

I punched the man's bodyguard, who cried in pain.

I tried to calm the man's wife, who cried hysterically, when she saw his injuries.

The first example could arguably, be said to be ambiguous. Who cried in pain? (we can deduce it is most likely the bodyguard but we have not actually written that). Whilst in the second example "who" is definitely the wife.
