Rob Gronkowski: Tight end has been making positive strides, but the educated guess here is that he'd like an increased level of comfort before taking the field.
Chris Jones: Rookie defensive tackle is a developmental prospect who has yet to dress for a game since being claimed on waivers from the Buccaneers.
Matthew Slater: Special-teams captain has already been declared out with a wrist injury.
Sebastian Vollmer: Starting right tackle missed practices Wednesday and Thursday with a foot injury, and while he returned for Friday's light practice, the feeling here is that he's more likely to play Oct. 6 in Cincinnati.
Leon Washington: Veteran running back was inactive last week with a thigh injury and remained limited in practice all week.
