The team also placed wide receiver Trent Taylor on the reserve/COVID-19 list and placed tight end Chase Harrell and fullback Josh Hokit on the practice squad COVID-19 list.
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 three additions mean the 49ers now have the following eight players on COVID-19 lists.
- TE Chase Harrell
- FB Josh Hokit
- QB Josh Johnson
- OL Colton McKivitz
- WR Trent Taylor
- RB Austin Walter
- WR Kevin White
- TE Charlie Woerner
