The chart shows each of the Cardinals' players with practice-squad eligibility, according to the team.

Practice-squad rules can be confusing, and exceptions sometimes apply to relatively experienced players. Brian St. Pierre has been around longer than most players with eligibility. He'll make the 53-man roster, though, so the practice squad won't be an issue for him.

I've categorized each player based on his perceived likelihood of earning a spot on the 53-man roster. Those are rough characterizations. Teams still have not made decisions. It's conceivable that a player listed as a "keeper" could face his release.

As noted: Rosters spots are serious business for NFL players lacking job security. For some, the next 30 hours or so will determine whether they'll earn $17,352.94 per week or whatever the real world pays.

The minimum NFL salary is $295,000. Players get paid in 17 installments, one for every week they spend as a paid member of the organization.

NFL teams must trim rosters from 75 players to 53 players by Saturday afternoon. Teams can establish eight-man practice squads beginning Sunday. Practice-squad players earn a minimum of $5,200 per week during the regular season and playoffs.

Once a player signs with a practice squad, he can practice with the team. He becomes eligible to play in games only if a team signs him to its 53-man roster. Practice-squad players are free to sign with any team's active roster at any time during the season.
