Sean McVay said on Wednesday that Matthew Stafford will not play on Sunday against the Kansas City Chiefs because of a neck injury.

After taking a hit in Week 11 against the New Orleans Saints, Stafford felt some numbness in his legs, but he was able to play the next day.

Stafford is in the concussion protocol as a result of some of the evaluations done this week, according to McVay.

Even though Stafford is in the concussion protocol, it doesn't mean he has suffered a concussion.

McVay said after Stafford was evaluated for a concussion, they wanted to take a conservative approach to taking him out of the game.

The Rams are taking it a week at a time, according to McVay. The coach wouldn't rule out shutting the quarterback down for the rest of the season.

Mc Vay said that Stafford is so tough. "He's such a great competitor and I definitely think that's one of those deals where if he is cleared, you definitely want to make sure that I'm making a smart decision for him and for our team."

John Wolford, who started in Week 10 when Stafford was in the concussion protocol, will be limited in practice due to a neck injury. He was not in the lineup for the game against the Saints because of his injury.

The game was played in New Orleans. Perkins is expected to take most of the quarterback snaps on Wednesday. He threw for 64 yards in relief of Stafford. He carried the ball for 39 yards.

Cookus was signed to the practice squad.
