What punctuation mark should be placed between the words town and he in sentence The manager will out of back until Monday?

The sentence "The manager will out of back until Monday" is grammatically incorrect and doesn't make sense. It seems like there's a word missing.

Here are a couple of possibilities and how they would be punctuated:

1. "The manager will be out of town until Monday." This is the most likely meaning. No punctuation is needed between "town" and "he".

2. "The manager will be out of back until Monday." This could mean the manager is out of the back office/room. Again, no punctuation is needed.

3. "The manager will be out of [something] until Monday." There could be another word missing, such as "the office", "state", or "reach". In this case, the punctuation would depend on the specific word used.
