Knox (calf) is listed as questionable for Sunday's game against the Seahawks.
Though Knox returned from reserve/COVID-19 list Thursday, he remained limited in back-to-back practices due to the calf injury that sidelined him back in Week 6. Given that Knox hasn't practiced fully since suffering the injury Oct. 13, the Bills may be hesitant to keep him active in Week 9. If Knox is ultimately sidelined or limited Sunday, Tyler Kroft would likely serve as the Bills' top tight end.
