call-up

A call-up refers to the process of assigning or summoning an individual—often a player or staff member—to a higher level or specific team, typically from a reserve or junior group. In sports, for example, a player might be called up from a minor league to the main team to fill a vacancy or for special games. It can also apply in military or employment contexts, where someone is formally ordered or invited to join a particular role or duty. The term emphasizes the act of officially bringing someone into a designated position or responsibility.
