Nasarawa state fa suspend footballer for slapping referee

I think there may be a slight mistake in your question. Nasarawa State FA is not a real entity, and I'm assuming you meant to ask about the Nigeria Football Federation (NFF) or the Nasarawa State Football Association (NSFA).

To answer your question, I couldn't find any recent information about a footballer being suspended by the Nasarawa State FA for slapping a referee. However, it's not uncommon for footballers to receive suspensions or fines for misconduct, including physical altercations with referees.

If you could provide more context or clarify which specific incident you're referring to, I'd be happy to try and help you find more information.
