Why do you 'severely doubt' it? The K is not a diamond so there's no reason whatsoever that villain isn't thinking 'he may have just AA or be making a c-bet so I'll take him off his hand with plenty of outs', like Kx89 with the k-high flush draw? He really doesn't need the nfd in his range of draws to be making this move with just a draw. The guy is prescribed as a regular as well, so he doesn't just checkraise with sets. Which is noobish, in case you didn't know.
