Kyle Juszczyk did not play during Sunday's loss to the Washington Redskins and it is looking likely that he will miss his second-straight game. Juszczyk, who is the only fullback on the on San Francisco 49ers roster, has not practiced with the team this week due to a back injury. Including last week, he has now missed five-straight full practices.

Rookie linebacker Reuben Foster continued to practice but was limited as he has been over the past two weeks. He was inactive against Washington but the 49ers are hopeful Sunday will be his first in-game action since September 10.

"He's moving around good," said 49ers defensive coordinator Robert Saleh on Thursday. "With a high-ankle sprain, you're always going to have little things here and there that pop up. He's one tough son of a gun so excited to see if he can get through the week so we can get him back in action."

Below are the official Thursday practice participation reports for both the 49ers and the Cowboys, as provided by the 49ers Communications department.
