An NFL team's practice squad is an important part of their roster. NFL teams can carry up to eight players on their practice squad as long as they have spent less than two years on a practice squad and have not been a part of a 53-man roster for six or more games.
The practice-squad players don't dress for game or even count for the final 53-man roster. They are practice players only, who can be called up during any week as long as someone else on the roster is either cut or put on the injured-reserve list.
Also, any team can sign a player from any other team's practice squad if they sign them to their 53-man roster. That means you don't want to put a rookie on your practice squad unless you aren't afraid of losing him.
We won't see any of the Philadelphia Eagles' draft picks on this squad, but we could see a few of their undrafted free agents becoming practice players only. Some of the more recent success stories from the Eagles practice squad have included Chad Hall, Cedric Thornton and Stanley Havili.
The key factor in having a successful practice squad is having a couple of players at positions where you are thin on the 53-man roster, keeping relatively unknown players who can add something extra in practice or develop into contributors down the road
