All three Rams starters who went through the NFL’s concussion protocol this week have been cleared to play.
Running back Zac Stacy, left guard Chris Williams, and cornerback Trumaine Johnson were all full participation in Friday’s practice and are listed as probable for Sunday’s contest at San Francisco.
Stacy, of course, has been a key cog in the Rams’ running game revival over the past seven games. He is second among all NFL rookies with 624 yards rushing and has a scored a touchdown in each of the Rams' past five games.
"I was disappointed to have to come out because I want to help my team," Stacy said about being injured against Chicago last Sunday. "I felt like I was fine. Absolutely, it was hard to come out of there, but you have to do what the doctors say."
Having Johnson back in the lineup is huge for the Rams because rookie cornerback Brandon McGee is questionable and did not practice Friday with a foot injury.
For Johnson, it was his first concussion since high school.
"I remember waking up and seeing (head athletic trainer) Reggie Scott's face and that was about it," said Johnson, who has five starts and two interceptions this season. "It was big-time scary when you can't remember things like that. I just pray to God that I'm not hurt now and that I've been cleared to play. I'm happy I'm back."
The game against San Francisco is one Johnson did not want to miss. He grew up a fan of the 49ers and Jerry Rice. Johnson will have many family members and friends at the game, which will be the last for the Rams at Candlestick Park.
"This is a big week; I'm going home," Johnson said. "I wanted to get back on the field as quickly as possible but, at the same time, you want to be safe."
At safety, rookie T.J. McDonald (shin) is questionable just one week after returning from a broken leg. He was limited in practice Friday.
If McDonald can’t go look for Darian Stewart back in the starting lineup.
Also on the Rams’ injury report: DE Eugene Sims (foot) full participation/probable; RG Harvey Dahl (knee) limited participation/questionable; LB Will Witherspoon (personal matter), did not practice/probable.
