Arik Armstead is a candidate to go on the injured reserve

Kyle’s update, 1:06 PM PT: Kyle Shanahan said Arik Armstead is dealing with separate foot and ankle injuries, and he’s a candidate to land on the injured reserve.

That would mean Armstead would miss the next four game against the Panthers, Falcons, Chiefs, and Rams. San Francisco has a bye week after, which may come in handy for Armstead and Javon Kinlaw.

Shanahan said there hasn’t been a decision or not yet on whether Armstead will go on the injured reserve, or if Jimmie Ward or would be activated. That will be decided on Saturday afternoon. Shanahan did say there’s a possibility for Ward to play.

Jason Verrett won’t be activated from the PUP list this weekend. Verrett will be needed on defense in January, not October. I’d assume the 49ers feel similar and will take their time with Verrett.

Shanahan wouldn’t commit to a starting right guard. On Thursday, offensive line coach Chris Foerster said backup Daniel Brunskill deserves reps during games. That sounds like the rotation between Spencer Burford and Brunskill will continue for another week.

Here’s a look at the final injury report:

OUT

DL Arik Armstead (foot, ankle)

DT Javon Kinlaw (knee)

RB Tyrion Davis-Price (ankle)

TE Tyler Kroft (knee)

OL Colton McKivitz (knee)

DB Tarvarius Moore (hamstring)

T Trent Williams (ankle)

49ers head coach Kyle Shanahan joined KNBR’s Murph & Mac Show Friday morning and shared injury news for his defensive tackles. He ruled out Arik Armstead and added that Javon Kinlaw is unlikely to play against Carolina.

Here’s Shanahan on Armstead:

“Arik’s not going to go this week. I’ll end up telling people that later, but yeah, we just had to rule him out. It’s week-to-week with him right now. Any time we don’t have Arik, we’re concerned. It’s something that was bothering him. He got a new thing on a different foot last game that just made it a little bit worse, and we’ve got to take it a little slower this week.”

The upcoming schedule allows the Niners to be patient with Armstead. They have the Panthers this week and the Falcons after. Both offensive lines are average at best.

Unfortunately, we won’t see Kinlaw this week either: “Odds are he’s not going to be able to go either. I haven’t talked to the trainers yet on whether we’ll officially rule him out, but he hasn’t been able to practice this week yet.”

After the Panthers and the Falcons, the 49ers get the Chiefs and Rams, then have a bye week. That will allow another week of rest before facing the Rams, Chargers, and Cardinals.

Ideally, you give Armstead and Kinlaw two weeks to heal, then get them back for a couple of weeks before another break. Then, the stretch happens. That’s when you want your best players on the field. And while the Niners have incredible depth along the defensive line, they’ll need their starting defensive tackles against the best of the best.
