Frank Gore went through a limited practice Thursday after sitting out the first two sessions of the week and is on pace to play Saturday against the Chargers, Jim Harbaugh said.
The 49ers’ all-time leading rusher was in a blue, non-contact jersey Thursday. That implies Gore is in the exertion stage of the league’s post-concussion protocol and must only pass the simulated-contact stage to be able to play Saturday.
On Wednesday Gore said he has felt “normal” since Sunday’s game. Still, passing the the final stage is not a mere formality. Right tackle Anthony Davis suffered a concussion Nov. 16 and remains in a blue, no-contact jersey this week.
Gore’s main backup, Carlos Hyde, has not practiced this week with an ankle injury. The team’s only healthy running backs are Alfonso Smith and Phillip Tanner, who was signed Wednesday.
In addition to Hyde, linebacker Chris Borland (ankle), receiver Stevie Johnson (knee) and cornerback Tramaine Brock (hamstring) did not practice. Receiver Michael Crabtree (knee), linebacker Michael Wilhoite (hip) and defensive end Justin Smith (back) were back after missing Wednesday’s practice. Cornerback Chris Culliver (knee) and linebacker Ahmad Brooks (thumb) also were wearing blue jerseys.
Jonathan Martin, who is Davis’ backup at tackle, was out with an illness.
