on the shelf

Awaiting future use

On the shelf describes something set aside, inactive, or no longer in use.

A project put on the shelf is postponed indefinitely.

The phrase once described unmarried women past the expected age for marriage—left unpicked like merchandise nobody wanted.

In sports, an injured player on the shelf is sidelined and unable to compete.
