Roster
Chiefly in North American sport, the official list of players on a team, subject to size limits and active or inactive designations.
Definition
A roster is the official register of players who belong to a team. The word is standard in North American sports, where leagues impose strict roster limits and distinguish the active roster — players eligible to play in a given game — from reserve, injured or inactive lists. Managing the roster through signings, releases, call-ups and roster moves is a central part of running a professional team.
Because roster spots are limited and often tied to salary rules, decisions about who occupies them carry competitive and financial weight. Outside North America the same idea is usually expressed as the squad, though 'roster' is increasingly used internationally, particularly in basketball, ice hockey and esports.
Scope: Chiefly North American usage; broadly equivalent to 'squad' elsewhere.
