49ers RB Brandon Jacobs didn't dress for the game despite being fully healthy and despite fellow running back Frank Gore's bruised ribs. Jacobs dressed for the team's most recent game, Oct. 18 against Seattle, but was the only 49er who didn't get into the game.
"I'm ready whenever coach calls my name," Jacobs said last week. "I can't do anything about what's going on, but I can work hard and show coach that I'm ready, that I'm healthy."
Brandon Jacobs is a non-factor in San Francisco.
