RC, Rex blast Rams for late-game execution (1:53)

The Rams executed poorly during the winning drive. There is a time and a place for it.

3:54 PM ET

Matthew Stafford has entered the concussion protocol, according to Sean McVay.

After the team's medical staff cleaned up after the game, they decided that it was the best thing for him to enter the protocol.

McVay didn't see any signs that Stafford was having a concussion. The appropriate thing for the person and the player in this instance is to put him in the protocol after Stafford was asked some questions after the game.

It's not for me to truly understand whether or not he has a concussion. There are necessary steps that need to be taken.

If Matthew Stafford isn't cleared to play by the time the Rams host the ArizonaCardinals on Sunday, John Wolford would play.

McVay said that Matthew would do everything in his power to be ready and that they would just take it a day at a time. John has done a great job when he has been in these situations. It wasn't too long ago that he had to come in in order to make the playoffs, and he did a great job.

The quarterback helped lead the Rams to a playoff spot in his first season in the league. In Week 17 he ran for 56 yards and threw for 231 yards.

Stafford has completed 68.4% of his passes this season for 1,928 yards, 8 touchdown and 8 pick ups.
