Both Breida and Sherman were listed as questionable on the 49ers' Friday injury report. Breida is dealing with an ankle injury while Sherman has been working through a calf injury.
"I'm pretty sure I'm playing this week," Sherman told reporters on Thursday. "Next Thursday, on Thursday, that's going to be a question for Thursday."
The 49ers play the Oakland Raiders on Thursday.
"I'm going to battle and try to hit both of them," Sherman added, "but the body can only do what the body can do."
