You can tell it's already Week 4 of the NFL season just by looking at the injury report. For the first few weeks of the season it wasn't filled with a ton of players, but with bumps and bruises starting to pile up, the injury report is getting a little crowded.
Wednesday's Lions injury report, for example, had a total of 15 players on it, nine of whom missed practice: WR Calvin Johnson (Ankle), WR Rashied Davis (Foot), OT Jason Fox (Foot), DE Kyle Vanden Bosch (Not Injury Related), DT Nick Fairley (Foot), LB Justin Durant (Concussion), CB Aaron Berry (Groin), S John Wendling (Knee) and S Louis Delmas (Abdomen). Five players were limited in practice: WR Maurice Stovall (Hand), TE Brandon Pettigrew (Shoulder), DE Lawrence Jackson (Hamstring), LB DeAndre Levy (Knee) and CB Eric Wright (Groin). Matthew Stafford was the only player on the injury report who fully practiced (he is dealing with a right forearm injury).
The Dallas Cowboys are also pretty banged up going into Sunday's game against the Lions. WR Miles Austin (Hamstring), OG Derrick Dockery (Knee), DE Jason Hatcher (Calf), CB Orlando Scandrick (Ankle) and K David Buehler (Groin) all were absent from Wednesday's practice. QB Tony Romo (Ribs), FB Tony Fiammetta (Hamstring) and WR Dez Bryant (Thigh) were limited in practice. RB Felix Jones (Shoulder), C Phil Costa (Knee), LB Anthony Spencer (Shoulder) and CB Mike Jenkins (Shoulder) were all listed on the injury report but fully practiced.
In the next two days we will get a much better idea of who will play on Sunday, although you can probably already rule out Davis, Fox and Fairley for the Lions. Davis was in a walking boot on Wednesday and is set to visit a foot specialist on Thursday. Actually, he is going to see the specialist that examined Fox and Fairley in August. Both players have been recovering from foot injuries since August, and although there was some talk that Fairley could debut on Sunday, it doesn't appear likely.
