Nwangwu (concussion) was a limited participant in Wednesday's practice.

EDGE Analysis

Nwangwu played eight snaps on special teams and returned a kickoff for 38 yards in the Vikings' Week 12 loss to the Bears, but he may have sustained a concussion at some point along the way. With the benefit of a Week 13 bye, Nwangwu was able to return to the field for the Vikings' first Week 14 practice, but he'll still need to upgrade to full participation by Friday and gain clearance from an independent neurologist in order to play Sunday against the Raiders. If available this weekend, Nwangwu would likely handle kick-return duties while serving as the No. 3 back behind Alexander Mattison and Ty Chandler.
