Jacobs (knee/Illness) didn't practice Thursday.
Jacobs was listed as a full participant Wednesday, though he appeared on the Raiders' injury report with a listed knee issue. Per Paul Gutierrez of ESPN.com, the running back missed Thursday's session due to an illness. We'll circle back on Jacobs' status no later than Friday's practice to determine whether his status for Sunday's game against the Chargers is in any danger.
