The Seahawks placed Lockett (undisclosed) on the reserve/COVID-19 list Thursday, John Boyle of the team's official site reports.
Lockett and Alex Collins (abdomen) are the second and third Seahawks to be placed on the list this season after Gerald Everett sat out Weeks 4 and 5 due a positive test of the virus. If Lockett is unable to suit up Sunday at the Rams, Seattle may be a bit compromised at wide receiver, as all of DK Metcalf (foot/back), Freddie Swain (ankle) and Dee Eskridge (foot) are tending to injuries at the moment.
