Notes

The 49ers' offensive line experienced multiple injuries during Monday night's game against the Baltimore Ravens. Trent Williams, Aaron Banks, and Jaylon Moore left the game and did not return. Among these three players, Williams is the only one who participated in practice every day this week and has been cleared to play this weekend.

"He's good," head coach Kyle Shanahan said of his veteran offensive lineman.

Wide receiver Jauan Jennings is still in the concussion protocol and will sit out a second consecutive game. When asked about the level of concern surrounding Jennings, Shanahan stated, "There's always concern. I don't want to talk too much about it because the protocol is very simple and how it goes, but he's had some real positive days here, I think, in the last few days. I think he's going in the right direction."

Rookie safety Ji'Ayir Brown suffered a knee sprain against the Ravens and has been ruled out against the Commanders. Shanahan noted, "He was fighting to go this week, so that means he has a chance next week (against the Rams)."

Defensive tackle Arik Armstead will miss his fourth straight game.

Below are Friday's practice participation reports for both the 49ers and Commanders, which were provided by the 49ers Communications staff.
