Jacobs is listed as questionable for Sunday's game against the Seahawks after he was a limited participant in Friday's practice with a calf injury, Rachel Gossen of the Raiders' official site reports.
Jacobs practiced fully Wednesday and Thursday, but the running back's addition to the injury report Friday makes his status worth monitoring ahead of Sunday's 4:05 p.m. ET kickoff. Ideally, added context with regard to Jacobs' status will arrive before the early wave of kickoffs this weekend, but if he's sidelined or available only in a limited capacity versus Seattle, more snaps at running back will be available for some combination of Ameer Abdullah, Brandon Bolden and Zamir White.
