By 3:00 PM CST on Tuesday, the Green Bay Packers must trim their roster from the current 90 eligible players down to just 53. Then, once that process is completed, and before they can fully turn their attention to the regular season, the Packers have to construct their 16-player practice squad.
Around the league, once these initial roster cuts are made, players with fewer than four accrued NFL seasons will go on waivers, where another team can put in a claim on them. Those with four or more accrued NFL seasons who are released become free agents right away and can sign wherever they please.
