Brandon Jacobs is a healthy inactive for Monday night's game against the Cardinals.
Jacobs wasn't on the injury report for the first time this week, so his inactivity is due to the successful combination of Frank Gore and Kendall Hunter. Anthony Dixon is the third running back due to his special teams prowess. Mario Manningham (shoulder) and LT Joe Staley (pneumonia) are active and will start. The rest of the San Francisco inactives are WR A.J. Jenkins, RB LaMichael James, OG Joe Looney, S Trenton Robinson, NT Ian Williams, and QB Scott Tolzien.
