The Las Vegas Raiders have placed four starting offensive linemen and safety Johnathan Abram on the reserve/COVID-19 list.

All five players were deemed high-risk contacts Thursday under the NFL's virus protocols, according to sources.

Las Vegas center Rodney Hudson, guards Gabe Jackson and Denzelle Good, tackle Kolton Miller join Trent Brown, who was already on the COVID-19 list. The Raiders could be without their entire offensive line for Sunday's game against the Tampa Bay Buccaneers.
