While four players were ruled out by the San Francisco 49ers for Saturday’s game against the San Diego Chargers, 10-year veteran running back Frank Gore, who suffered a concussion Sunday in Seattle, was not among them. In fact, Gore, who is in the final year of his contract, is expected to play in the season’s penultimate game.

Gore is officially listed as questionable, as are four other staters in receiver Michael Crabtree, right tackle Anthony Davis and linebackers Ahmad Brooks and Michael Wilhoite.

Rookie running back Carlos Hyde is out, so third-stringer Alfonso Smith figures to spell Gore, so long as Gore, who was limited in practice Thursday and Friday after sitting out Wednesday, is able to play. Otherwise, Smith is the Niners’ starting running back.

And with rookie inside linebacker Chris Borland out, Nick Moody will start in his place.

The following is the 49ers’ status report for the Chargers game:

OUT: LB Chris Borland (ankle), CB Tramaine Brock (hamstring), RB Carlos Hyde (ankle), WR Stevie Johnson (knee)

QUESTIONABLE: LB Ahmad Brooks (thumb), WR Michael Crabtree (knee), RT Anthony Davis (concussion), RB Frank Gore (concussion), S Raymond Vetrone (groin), LB Michael Wilhoite (hip)

PROBABLE: CB Perrish Cox (ankle), CB Chris Culliver (knee), DT Quinton Dial (knee), DE Tony Jerod-Eddie (foot), RT Jonathan Martin (illness), C Marcus Martin (knee), LS Kyle Nelson (back), DE Justin Smith (back)
