49ers-Seahawks Injury Report: Jaquiski Tartt, Kwon Alexander ‘doubtful’ for Sunday; Jimmie Ward ‘questionable’

The San Francisco 49ers are preparing for their Week 8 contest against the Seattle Seahawks on Sunday at CenturyLink Field in Seattle, Washington.

Safety Jaquiski Tartt did not practice this week as he continues to recover from a groin injury. He has been listed as "doubtful" for Sunday. As has linebacker Kwon Alexander, who has been sidelined since suffering a high-ankle sprain during Week 5.

The 49ers' other starting safety, Jimmie Ward, has been listed as "questionable" to play due to a quadricep injury. Defensive lineman Kentavius Street shares the same status with Ward, but due to an illness. As is the protocol with any illness, he has one more COVID-19 test to pass before he can rejoin his teammates. Head coach Kyle Shanahan said that will likely mean flying on his own to Seattle for Sunday's game.

Below are the official injury reports for the 49ers and Seahawks, which were provided by the 49ers Communications staff. Also included are Friday's practice participation reports.
