Nwangwu (concussion) was a full participant in Friday's practice and does not carry an injury designation ahead of Sunday's game against the Raiders.
Nwangwu logged a full practice session Thursday after being limited Wednesday. His lack of an injury designation indicates that he was able to clear the NFL's five-step concussion protocol. He'll provide backfield depth Sunday behind Alexander Mattison and Ty Chandler while operating as the Vikings' main kick returner.
