Jacobs (ankle) is considered doubtful for Sunday's game against the Dolphins, Paul Gutierrez of ESPN.com reports.

EDGE Analysis

With Jacobs trending toward his second straight missed game, Kenyan Drake and Peyton Barber once again are in line to share the Raiders' backfield duties this weekend. It's an arrangement that yielded Drake seven carries for nine yards and five catches for 46 yards (on 47 snaps) and Barber 13 carries for 32 yards (on 19 snaps) in the Raiders' Week 2 win over the Steelers.
