Sheldon Richardson's 2021 season — his second with the Vikings and ninth in the NFL — is thus far the first in the defensive lineman's career where he hasn't started a game.
That could change on Sunday, as the Vikings give Richardson an enhanced role on a defensive front that lost two more starters this week.
Dalvin Tomlinson will miss the game while on the COVID-19 reserve list, and Everson Griffen could be away from the Vikings for some time after he was taken by ambulance from his home to a mental health facility on Tuesday.
