SANTA CLARA -- Jim Tomsula said Monday that Carlos Hyde (foot), receiver Anquan Boldin (hamstring) and cornerback Tramaine Brock (shin) would continue to be day to day with their injuries. None played in the team's Week 9 win over the Falcons and Hyde, who is dealing with a stress fracture in his left foot, hasn't played since Oct. 22.
Boldin, meanwhile, has missed the last two games with a hamstring pull that has moved from the top of the muscle to the bottom. Tomsula said the team's medical staff wanted to be cautious with an injury that behaved like that.
"None of those guys have gone full speed, nobody's done anything at full tilt yet," Tomsula said. "So we'll see where that's at."
He said outside linebacker Aaron Lynch (finger, ankle), cornerbacks Kenneth Acker (concussion) Marcus Cromartie (face), Keith Reaser (ankle) and safety Jimmie Ward (ankle) will be full go in practice this week.
Hyde played with his injury for two and a half games. But the pain was so severe at one point during an Oct. 18 win over the Ravens that he crumpled to the ground without being hit.
Orthopedists have said that a month is not enough time for the fracture to heal on its own. But the hope is that Hyde's foot feels better and that the pain level has diminished.
"He's feeling better with all those things," Tomsula said. "But you don't know (until) you play."
Hyde has been maintaining his conditioning -- mostly on an exercise cycle -- over the last month but has done little running.
Shaun Draughn starting the most recent game at running back with Kendall Gaskins and Pierre Thomas also getting carries. The 49ers have since replaced Thomas with Travaris Cadet because, Tomsula said, he is more of a change-of-pace runner than Thomas.
