The 49ers suffered another blow to a crucial defensive player on Monday, when Kyle Shanahan announced during his press conference that defensive lineman Arik Armstead will be out indefinitely with a broken hand sustained in San Francisco’s loss to the Redskins.
Arik Armstead broke his hand and will require surgery. He’ll be out for a while.

“He’s going to need surgery, so it’s going to be some time,” Shanahan said of Armstead, the 49ers’ first-round pick in the 2015 draft.
Shanahan also announced that pass-rusher Aaron Lynch will be out for at least a week with a calf strain.
“The more guys you lose, the less you like that depth,” Shanahan said. “Losing Arik, which could be some time. We’ll have to discuss IR. We have to do that over the next couple of days. We know we’re going to have Lynch out, too, for at least a week or most likely more. That takes away two guys who were helping.”
If Armstead is indeed out for the season, the 49ers will have to add a player to their 53-man roster. Armstead, 23, has 1.5 sacks and 13 tackles so far this season
