SANTA CLARA, Calif. -- There were no surprises on the San Francisco 49ers injury report Friday.As expected, linebacker Patrick Willis (groin), tight end Vernon Davis (hamstring) and tackle Anthony Davis (shoulder) were all listed as questionable. Willis is probably the biggest question.But if he doesn't have a setback Willis could play. He missed last week's game at St. Louis with a groin injury that knocked him out of the third quarter of a Week 3 loss to the Colts.
