Defensive tackle Javon Kinlaw and cornerback K'Waun Williams missed their second consecutive practice of the week. Defensive tackle Kevin Givens is away attending to what head coach Kyle Shanahan said was "a family matter."
The others who did not practice — Brandon Aiyuk, Deebo Samuel, Richard Sherman, Trent Williams, and Jordan Willis — have already been ruled out for Sunday's game.
The only change from Wednesday's practice is that linebacker Mark Nzeocha was limited. He did not practice on Wednesday.
