SANTA CLARA, Calif. -- Receiver Jon Baldwin and running back LaMichael James are surely not the missing links to the San Francisco 49ers' offensive woes.But they might get a chance to see if they can make an impact in the offense, which has scored a combined 10 points in the past two games.The 49ers' receivers beyond Anquan Boldin have been unable to get open in the two losses. The team missed tight end Vernon Davis, held out of Sunday's loss due to a hamstring injury.
