Ruckert (knee) was a limited participant in practice Thursday.
Ruckert marked his second straight limited practice in preparation for Week 4. The 26-year-old likely suffered the knee injury in the Jets' Week 3 loss to the Lions, when he hauled in five targets for 39 yards and a touchdown. If his status doesn't improve, the fifth-year pro could be in danger of missing Sunday's contest against the Bears.
