Knox (calf/illness) isn't practicing Wednesday, Joe Buscaglia of The Athletic reports.
Knox remains on the reserve/COVID-19 list, though he'll be eligible for activation once 10 days have passed since his last negative test. The tight end was battling a calf injury at the time of his placement on the list, so he'll have multiple issues to heal up from before he's able to practice again. At this point, Knox looks unlikely to gain clearance for Sunday's game against the Seahawks.
