The University of Oregon said it is looking into a video that surfaced which shows Ducks outside linebacker DJ Johnson striking a person in Oregon State gear on the field after Saturday's civil war game at Reser Stadium.
In the video, Johnson can be seen punching a person from behind. He is then restrained and led away by what appears to be two Oregon staff members.
''We are aware of a postgame exchange involving a member of our football team and a fan and are working to gather more information,'' the Oregon athletic department said in a statement, according to the Associated Press.
''We are (aware) of this matter and are confident that the Pac-12 Conference and the University of Oregon will investigate this matter and deal with it appropriately,'' Oregon State spokesman Steve Clark said in a statement to The Associated Press.
Clark said the university does not know the identity of he person who was punched and hoped he person is not injured. No complaint has yet been filed with the university's police department as of Sunday afternoon.
