- WR Brandon Aiyuk
- TE Daniel Helm
- DT D.J. Jones
- DL Javon Kinlaw
- LB Joe Walker
- T Trent Williams

The reserve/COVID-19 list has been created for a player who tests positive for COVID-19 or has been quarantined after having been in close contact with an infected person or persons. If a player falls into either of these categories, his club is required to immediately place the player on the reserve/COVID-19 list.
Clubs are not permitted to comment on a player's medical status other than referring to the roster status and may not disclose whether the player is in quarantine or is positive for COVID-19.
The 49ers are scheduled to play the Los Angeles Rams at SoFi Stadium on Sunday.
