Jacobs (shoulder) logged a limited practice Wednesday, Paul Gutierrez of ESPN.com reports. "[Jacobs] made some improvement, but he still has to go to there and move explosively [Thursday] and Friday and do the things a running back has to do to play in this league and protect himself in this league," coach Jon Gruden said after practice. "So, we'll see what happens in the next 48 hours."
Jacobs' participation to start Week 15 is a good sign, but coach Jon Gruden has yet to sign off on the running back returning to action Sunday against the Jaguars. If Jacobs is able to suit up this weekend, DeAndre Washington would presumably revert to a complementary role after heading the Oakland backfield in the Week 14 loss to the Titans.
