Players who are eligible for PS (like rookies, UDFA, etc).
This wont be available until after Week 4 Preseason.
Here's the breakdown.
Each NFL team may keep up to ten members on its practice squad in addition to the 53-member main roster. A majority of those on a practice squad are
rookie draft picks and
Undrafted Free Agents (UDFAs) who were cut in training camps. A practice squad also includes veterans. Players may be signed to a practice squad for several reasons: for lack of space on the team, due to injury, or because they require more development.
A player cannot participate on the practice squad for more than three seasons; he is eligible for a third season only if the team has at least 53 players on its active/inactive list for the duration of that player's employment, or have no prior accrued seasons in the NFL (an accrued season is six or more games on the active roster); or if he has accrued a year of NFL experience on a club's 53-man active roster. If the player was on the active list for fewer than 9 games during their "only Accrued Season(s)", he maintains his eligibility for the practice squad. Games in which a player is listed as the third-string quarterback (a designation that has been abolished as of 2011) do not count as being on the active list.
