SANTA CLARA -- Left tackle Joe Staley missed his second straight practice after suffering a knee injury Sunday against the Packers. Linemate Alex Boone (ankle) missed Wednesday’s session but was on hand for Thursday’s session.
On Wednesday Jim Tomsula said both players were “fine.”
“We just need to make sure,” he said. “Boone got that ankle rolled up and Joe got rolled up on the leg. So just going to give it that extra day here today. They’re going to do all the walk-throughs and everything and then they’ll be out there (Thursday).”
If Staley couldn’t play Sunday, Boone likely would start at left tackle and either Ian Silberman or Brandon Thomas would fill in at left guard
In addition to Boone, receiver Quinton Patton (concussion) returned to practice. Patton was wearing a blue, non-contact jersey, signaling that he is progressing through the league’s post-concussion protocol.
Tight end Vernon Davis (knee) and linebacker NaVorro Bowman (veteran day Wednesday) also were at Thursday’s practice.
