He won't last for tomorrow

[keramus]

Hello everybody

A terrorist attack happened and a man was shot in the heart. He was taken to the hospital. The doctor said to his wife:
I'm afraid he won't last for tomorrow.
Does the highlighted part sound correct and natural in English?

Please tell me your opinion.

Where did you see this?

I made up this story to provide context. I looked up "last" in Cambridge dictionary and it says: to continue to exist.
For this reason, I decided to ask this question.

The problem with your sentence is "He won't last for tomorrow." It makes it sound as though there is something special happening tomorrow but he will miss it. ("Doctor! I don't care if he dies, I only want him to live long enough to sign papers tomorrow! Will he live that long?" -- "No. He will not last long enough to do that.")

The most common way to say this is "He won't last the night." or "He won't last a week." But this sounds quite cold and would be a rude way for a doctor to give such bad news.

I agree.

He might also say 'He won't last till tomorrow'. But again, it's far colder and more direct than a doctor is ever likely to be.
