Scott Wells and Steven Jackson joined Danny Amendola and Robert Quinn on the sidelines at Wednesday's practice.
The St. Louis Rams had four starters missing from the team's practice on Wednesday, according to Turf Show Times' Ryan Van Bibber. Center Scott Wells, running back Steven Jackson, wide receiver Danny Amendola and defensive end Robert Quinn all sat out with injuries.
Wells is coming off of his first full game since Week 1, meaning his absence from practice was likely for rest purposes. Jackson was likely the recipient of a rest day as well, as the Rams used a similar approach with the star tailback a week ago.
Amendola was back in a walking boot on Monday, and his status for this weekend's game is up in the air. He missed the entire second half of the Rams' Week 12 win over the Arizona Cardinals.
Quinn suffered an apparent concussion on Sunday, and has yet to be cleared to play.
The Rams host the San Francisco 49ers at Edward Jones Done on Sunday. Game time is set for noon CT, with FOX handling the TV broadcast.
