Practice squads can be comprised of players who were released by other teams so long as they went unclaimed on waivers. Usually, teams opt to bring back their own guys but players released by any team are up for grabs. Of course, the practice squad does have some restrictions so it doesn’t apply to every single player.
Here are the rules of eligibility for a practice squad:
- Teams can have up to 10 players who are eligible to practice with the team throughout the season. They are not eligible to play on regular-season games unless moved to the 53-man roster.
