"As expected, San Francisco 49ers running back Frank Gore is active for Sunday's tilt against Arizona, while the Cardinals will play a third straight week without quarterback Kevin Kolb.

Gore hyperextended his right knee during the Niners' Week 10 win over the New York Giants and did not return to practice this week until Thursday. Gore went down early against the Giants and finished the game with just six carries for zero yards -- his first career game without a yard."
