Jacobs was dealing with an ankle injury heading into Week 12 before running all over the Seahawks. Now dealing with a calf injury, Jacobs is not expected to practice much, if at all, this week because of the calf strain, Pelissero said in his tweet. Pelissero added Jacobs will get around-the-clock treatment. If he can't go, White and Abdullah would likely split up the workload.
The Raiders are currently carrying five running backs (plus a fullback), so if Jacobs really loses this much ground game work to rookie Zamir White, the veteran's fantasy season is going to be miserable. Amongst those other running backs resides Brandon Bolden, who has a rich history of catching passes out of the backfield in a Josh McDaniels offense.
Raiders beat writer Maurice Morton added to Pelissero's tweet that he's "not surprised about this." He said Abdullah hasn’t played the last 2 preseason games and he clearly surpassed Drake on the Raiders RB depth chart. In his eyes, the depth chart goes: Jacobs, White, Abdullah and Bolden. Drake could catch on somewhere else but his role may not be as significant as it once was.
