Coach Jon Gruden said Monday that Jacobs (toe/ankle) is day-to-day and "very questionable" to face the Dolphins in Week 3, Adam Hill of the Las Vegas Review-Journal reports.
Jacobs wasn't able to suit up against the Steelers in Week 2, and it looks like he's no lock to return to full health in time to face Miami. Kenyan Drake was out-carried by Peyton Barber in Jacobs' absence Sunday, but neither running back managed much in the way of efficiency on the ground against Pittsburgh's stout defensive front.
