Starting tackle Nick Kaczur and defensive end Jarvis Green were inactive for the second straight week for the Patriots with injuries. Other inactives for New England were wide receiver Matthew Slater, cornerback Lewis Sanders and linebackers Eric Alexander and Shawn Crable.

For St. Louis, the other inactive players were defensive tackle Adam Carriker, cornerback Tye Hill, safety Todd Johnson, guard Roy Schuening, wide receiver Drew Bennett and tackle John Greco. Brock Berlin was listed as the third quarterback.
