Each team is permitted to have 55 players on its roster; however, only 48 may be active (eligible to play) on game day.  Each team is also allowed 12 additional players on a "practice squad"; any team can sign a player from another team's practice squad to its main roster without compensating the other team.  A player may be elevated from the practice squad to the roster (and returned) only twice during a season; on the third elevation the player must remain on the roster for the remainder of the season.

A team may also designate an "emergency" third quarterback for games (this rule was implemented in 2023 after a disastrous 2022 playoff game when a team was forced to use a wide receiver after its two quarterbacks were injured and unable to continue)

The NFL has a strict salary cap rule: before each season it announces the amount each team can spend on all players (including payments to players no longer on the roster) and, unlike other leagues which have exceptions or luxury taxes, the amount announced is the true maximum which can be spent.  It does not, however, have a salary floor (a minimum amount which must be spent), but most teams are at or near the cap.

The NFL does not operate a minor league system nor does it have working arrangements with any other football league (such as the [[Canadian Football League]]) for player development.  A player may be drafted (or, if not drafted, sign as an undrafted free agent) once the player has been out of high school for three seasons.  A player may declare himself eligible for the draft and is permitted a window whereby he can revoke his decision, except if the player has signed with a sports agent the decision is irrevocable.
