gone on a personal emergency;

[musicgold]

Hi,

I heard a native speaker saying the following sentence. I tried searching the sentence on Google but couldn’t find anything like that. Is it correct English?

John has gone on a personal emergency; I will fill in for him and answer your questions.

Thanks,

MG.
