The 49ers secondary is the biggest concern heading into the game. If Jaquiski Tartt (shoulder) is unable to play, it will likely feature Ahkello Witherspoon and Jimmy Ward as the cornerbacks with Adrian Colbert and Antone Exum as the safeties. Cornerback Richard Sherman (calf) has been ruled out while Tartt is doubtful. Colbert (hip) is listed as questionable.
Guard Mike Person did not appear on Friday's injury report. Head coach Kyle Shanahan was asked if he is "back to normal."
"It depends on what you consider normal, but he's good to go," he responded.
Matt Breida (knee) is listed as questionable. Shanahan said the running back had been up and down during practices this week and the team will see how he feels on Sunday before determining his status.
"He got a little bit more yesterday," he said. "We kept him limited today. Just trying to manage the wear and tear. But questionable is better than doubtful so hoping it works out."
Below are the official injury reports for the 49ers and Chargers. Also included are Friday's practice participation reports, which were provided by the 49ers Communications staff.
