SANTA CLARA – Running back Carlos Hyde and linebacker Chris Borland are scheduled to undergo MRI examinations on ankle injuries sustained in the 49ers’ 17-7 loss to the Seattle Seahawks on Sunday.
Hyde and Borland are among six players who sustained injuries in Seattle that place their availability for Saturday’s game against the San Diego Chargers in question. Borland played one snap in the second half, but could not continue.
Hyde said he also injured his back on a third-quarter running play on which Seattle linebacker Bobby Wagner pulled him down for no gain. The team’s training staff re-wrapped Hyde’s right ankle on the sideline, but he did not return.
“I just went down awkwardly,” Hyde said. “I was trying to torque my body . . . I was trying to dip my shoulder but he caught on to me and pulled back.”
Running back Frank Gore, who sustained a concussion in the second quarter and did not return, much pass the NFL’s protocol on concussions before he is allowed to return to action.
“They said he’s feeling good,” Harbaugh said after the team’s medical staff spoke with Gore.
Right tackle Anthony Davis has missed four games with a concussion, and he is making progress. Harbaugh said if Davis cleared, he will return to action for the final two games.
“We’ll be looking for all available personnel to play,” Harbaugh said. “That’s a medical question.”
Outside linebacker Ahmad Brooks sustained a dislocated thumb in the second quarter and did not return. Harbaugh said he did not know the extent of Brooks’ injury or whether he will be able to return before the end of the regular season.
Special-teams ace Kassim Osgood will not play again this season, Harbaugh indicated. Osgood sustained a broken hand in the team’s loss to the Seahawks and still managed to record two special-teams tackles.
“He broke that early in the game and padded it up and was playing in a lot of pain and made plays,” Harbaugh said. “That’s an example of valiant effort.”
