FILE - In this Jan. 2, 2017, file photo, Oklahoma running back Joe Mixon (25) celebrates his touchdown against Auburn in the first half of the Sugar Bowl NCAA college football game in New Orleans, Monday, Jan. 2, 2017. Oklahoma receiver Dede Westbrook believes Joe Mixon should be at this week's NFL's scouting combine. Mixon was absent during Friday's, March 3, 2017, running back workouts because a league policy bars players convicted of violent crimes from attending. Mixon and Westbrook were college teammates.
