SANTA CLARA -– Running back Carlos Hyde did not practice again on Thursday due to a stress fracture in his left foot and appears unlikely to be available Sunday when the 49ers face the Seattle Seahawks.

The Seahawks, meanwhile, have their own running back issue. Marshawn Lynch did not practice for the second consecutive day due to an abdominal strain.
