Steelers linebacker Ryan Shazier, a first-round pick in 2014, single-handedly shut down the 49ers on Sunday, with 15 tackles, three tackles for loss, a sack, a forced fumble, and a fumble recovery. For his effort, he has emerged with a shoulder injury.

According to the official injury report, Shazier missed practice on Wednesday.

The Steelers will need him to play, and to continue to play well, if they want to keep winning games. Especially since the rest of the defense isn’t nearly as stout as it used to be.

And especially since Todd Gurley could be making his debut this weekend for the Rams.
