Rams cornerback Trumaine Johnson suffered a concussion during Sunday's game and will go through the league's concussion protocol this week, reports ESPN.
Meanwhile, Chase Reynolds sustained a knee injury and will need more examinations before the severity is determined.
Rams running back and special teamer Chase Reynolds signed his one-year tender as an exclusive rights free agent on Tuesday, according to the St. Louis Post-Dispatch.
Reynolds is one of the core special teams players for the team, missing only one game in the last two seasons. He finished the 2014 season with a team-high 19 special teams tackles.
Linebacker Jo-Lonn Dunbar, who was questionable with a thigh injury, is among the injured Rams cleared to face the Seahawks. He has 20 tackles in five games. Also suiting up are defensive tackle Alex Carrington (knee), center Barrett Jones (back) and running back Chase Reynolds (thigh).
The Rams have listed wide receiver Austin Pettis (ankle), running back Zac Stacy (ankle), defensive tackle Alex Carrington (knee), running back Chase Reynolds (thigh) and offensive lineman Barrett Jones (back) probable for Week 7 at home against the Seahawks.
Meanwhile, linebacker Jo-Lonn Dunbar (thigh), defensive end Ethan Westbrooks (hand), cornerback Trumaine Johnson (knee) and cornerback Brandon McGee (foot) all practiced at a limited capacity and were each deemed questionable for Sunday. Center Tim Barnes was the only player ruled doubtful for the divisional clash.
The Rams declared cornerbacks Trumaine Johnson (knee) and Brandon McGee (foot), running back Chase Reynolds (hip), defensive tackle Alex Carrington (knee), offensive lineman Barrett Jones (back), wideout Chris Givens and quarterback Case Keenum inactive for Monday's game against the 49ers.
Givens is a healthy scratch for the second straight game.
The Rams have listed four players as questionable Week 6 against San Francisco.
Chase Reynolds, Jo-Lonn Dunbar, Barrett Jones and Alex Carrington will all be game-time decisions heading into Sunday. Dunbar is dealing with a groin issue.
Rams rookie running back Tre Mason has a long way to go to earn meaningful snaps. The team's first depth chart lists him on the fourth team, behind starter Zac Stacy, backup Benny Cunningham and third-stringers Isaiah Pead and Chase Reynolds.
A third-round draft pick, Mason shares the fourth line of the depth chart with undrafted back Trey Watts.
Rams defensive back Cortland Finnegan (eye), defensive back Matt Giordano (thigh), running back Chase Reynolds (knee) and defensive back Darian Stewart (foot), who were all listed on Friday's injury report, are active for Week 12 against Chicago.
Rams DB Matt Giordano, RB Chase Reynolds and S Darian Stewart are probable Week 12 against the Bears.
Both Stewart and Giordano were limited in practices this week. Reynolds was unable to practice Wednesday and Thursday due to a knee injury.
Notable players cut by the Rams Friday include: DT Cornell Banks; QB Tom Brandstater; DE Mason Brodine; LB Aaron Brown; LB Sammy Brown; DB Kendric Burney; QB Kellen Clemens; DE Vernon Gholston; TE Ben Guidugli; TE Cory Harkey; DE Jamaar Jarrett; WR Nick Johnson; FB Ovie Mughelli; TE Deangelo Peterson; RB Chase Reynolds and DE Scott Smith.
