When the owners and players voted on the new CBA earlier this spring, one of the selling points bandied about by the media was the fact that the new agreement included roster expansion. Specifically, teams would be able to carry 55 players rather than 53, with practice squads expanding from 10 players to 12 players.
While it’s true that teams will be able to carry 55 players on the active roster, that expansion is basically only available for game days. Teams will continue to field a 53-player active roster, however, on game days teams will have a new option, which is (bolding added is mine):
Article 33, Section 5
(b) In each game of the regular and postseason, a Club may choose to elevate a maximum of two players from its Practice Squad to its Active/Inactive List without the player first terminating his Practice Squad Player Contract and executing an NFL Player Contract.
