It seems the 49ers will have at least one of their starting defensive tackles against the Baltimore Ravens on Monday Night.

Javon Hargrave returned to practice on Friday after missing the past game with a hamstring injury, which means he has a legitimate chance to play this week. Meanwhile, Arik Armstead remains out with a knee injury that has cost him the past two games, which means he very well could miss a third game in a row.

Hargrave seemed spry and rested as he went through the defensive line drills on Friday, while Armstead was nowhere to be found. Most of the time, injured players rehab or jog on the side of the field while they’re out. Not Armstead. He hasn’t made an appearance at practice since last week, when he walked off the field while the rest of the players were beginning their work.

Getting Hargrave back would be a huge boost for the 49ers, because he’s their second-best pass rusher after Nick Bosa. But the 49ers’ biggest task against the Ravens will be stopping the run, considering the Ravens have the second-best rushing attack in the NFL. And Hargrave isn’t a great run defender.

Armstead is elite against the run. Teams can’t move him out of his gap. He engulfs offensive linemen and running backs with ease. If he doesn’t play, the 49ers could really struggle to stop the run, considering their run defense statistically is sub par even with him on the field.

We’ll see if Armstead participates in the 49ers’ walk through on Saturday. If not, you can probably forget about him playing on Christmas.
