Murray (concussion) did not participate in practice Wednesday, Scott Bair of CSN California reports.
It's unclear exactly where Murray is in the NFL's concussion protocol at this stage, so his status will be worth tracking closely in advance of Sunday's game against the Vikings. Taiwan Jones, who is listed as the Raiders' No. 2 RB, had as many fumbles (two) as carries in Week 9, so if Murray is out or limited this weekend, the team could lean more heavily on the likes of fullbacks Marcel Reece and Jamize Olawale, with Roy Helu an option to rejoin the team's backfield mix Sunday after being inactive this past weekend.
