The Chargers placed Marshall on the reserve/COVID-19 list Monday.
According to Jeff Miller of the Los Angeles Times, head coach Brandon Staley labeled Marshall as day-to-day, which would seem to suggest that the 25-year-old safety is on the list as a vaccinated player that tested positive for the virus. Per the NFL's new COVID-19 protocols, Marshall will be eligible to rejoin the team as soon as he's deemed to be asymptomatic. Marshall thus has an outside shot of gaining clearance prior to Sunday's game against the Texans. He's appeared in 12 games to date this season, recording 19 tackles.
