The Chargers activated Cook (illness) from the reserve/COVID-19 list Wednesday, Daniel Popper of The Athletic reports.
Cook is set to return to the lineup Sunday against the Raiders after missing the Chargers' Week 17 win over the Broncos, a game in which Tre' McKitty and Stephen Anderson shared the team's tight-end duties. Through 15 games to date, Cook is averaging 2.9 catches (on 5.1 targets) for 32.3 receiving yards to go along with four touchdowns.
