Kroft won't practice Wednesday due to a back injury, Ethan B. Greenberg of the Jets' official site reports.
Since logging three catches for 26 yards Week 1, Kroft, who played through a rib issue this past Sunday against the Titans, has totaled just three catches for 20 yards over the Jets' subsequent three contests. If Kroft ends up sitting out this weekend against the Falcons, Ryan Griffin would operate as the Jets' clear No. 1 tight end after splitting work with Kroft through the first four contests.
