Cook (illness) remains on the reserve/COVID-19 list ahead of Sunday's game against Broncos, Gilbert Manzano of The Orange County Register reports.
Until Cook clears the NFL's COVID protocols, the Chargers will rely on Stephen Anderson, Tre' McKitty and Hunter Kampmoyer to handle the team's tight end duties, with Cook's top backup for most of the season, Donald Parham (concussion), on injured reserve.
