With Brady Poppinga and Mike Neal officially on injured reserve, the Packers have nine players on the list. That's more than any team in the league, with New England, San Diego, Cleveland and Jacksonville with eight apiece and Indianapolis and St. Louis with seven, according to our research.
The Packers' list includes starters Jermichael Finley, Morgan Burnett, Nick Barnett and Ryan Grant. The others are Derrick Martin, Justin Harrell and Josh Bell. The Packers arguably have lost more impact players than any team in the league.
Here's the rundown. Teams are listed by division, in order of the standings:
GREEN BAY: 9. Key players: Finley, Barnett and Grant were three of the Packers' most important players.
CHICAGO: 2. Key player: LB Hunter Hillenmeyer started 13 games last season and was expected to be a key backup this year.
MINNESOTA: 2. Key player: CB Cedric Griffin, who tore his left ACL in the NFC championship game last year, is out with a torn right ACL.
DETROIT: 6. Key player: LB Jordan Dizon was a key player on special teams.
N.Y. GIANTS: 5. Key player: S Michael Johnson had started at safety the past two seasons.
WASHINGTON: 3. Key player: WR Malcolm Kelly caught 25 passes as a part-time starter last year.
DALLAS: 1.Key player: None, but Tony Romo's broken left clavicle from Monday night will sideline him for about eight weeks.
ATLANTA: 2.Key player: RB Jerious Norwood, the backup for star Michael Turner, had a career rushing average of 5.3 yards.
TAMPA BAY: 2. Key player: None.
NEW ORLEANS: 4. Key player: None, but the Saints have been without RB Reggie Bush since Week 2 with a broken leg. He might return this week.
CAROLINA: 4. Key player: None.
SEATTLE: 3. Key player: LB LeRoy Hill is a former Pro Bowler who had fallen out of favor with off-field issues. G Max Unger started all 16 games last year as a rookie.
ARIZONA: 1. Key player: None.
ST. LOUIS: 7. Key player: WR Donnie Avery caught 100 passes with eight touchdowns in his first two seasons. WR Mark Clayton picked up a lot of that slack and was becoming Sam Bradford's go-to receiver, with 22 catches in four games.
SAN FRANCISCO: 3. Key player: None.
NEW ENGLAND: 8. Key players: DE Ty Warren is one of the top 3-4 ends in the league. CB Leith Bodden, who was re-signed with a four-year, $22 million deal in the offseason, is a solid starter with 12 picks over the previous three seasons. RB Kevin Faulk is a premier third-down back.
MIAMI: 6. Key players: CB Will Allen had been a full-time starter since entering the league in 2003. DE Jared Odrick was their first-round pick.
BUFFALO: 2. Key player: None.
PITTSBURGH: 3. Key player: T Willie Colon was a three-year starter.
BALTIMORE: 5. Key player: CB Domonique Foxworth started all 16 games last year with four interceptions.

HOUSTON: 8. Key players: LB DeMeco Ryan was a tackling machine who had started all 64 games and is a two-time Pro Bowler. DE Connor Barwin had 4.5 sacks last year as a rookie.
INDIANAPOLIS: 7. Key players: This list does not include hard-hitting safety Bob Sanders, who tore a biceps tendon. The Colts are holding out hope that he might return for the playoffs. TE Dallas Clark was Peyton Manning's go-to receiver. He was on pace for a second consecutive 100-catch season.
JACKSONVILLE: 8. Key player: None.
KANSAS CITY: 5. Key player: TE Brad Cottam was a part-time starter and top blocker.
OAKLAND: 2. Key player: None.
DENVER: 3. Key player: If any player is a bigger loss than Finley was to the Packers, it's LB Elvis Dumervil, who led the NFL with 17 sacks last year.
SAN DIEGO: 8. Key player: LB Shawne Merriman is the only "name" player in the group. But, since recording 39.5 sacks in his first three seasons, Merriman had none in one game in 2008, four in 14 games in 2009 and none in three games this year.
