SAN DIEGO -- Even though they signed running back Kenjon Barner to a one-year deal this week, the Los Angeles Chargers continue to do their homework on running back prospects in this year's draft.
And that work includes bringing in University of Oklahoma product Joe Mixon for a pre-draft visit on Tuesday and Wednesday, according to ESPN's Jim Trotter.
Mixon already visited two other AFC West teams in the Oakland Raiders and Denver Broncos, along with the Cincinnati Bengals.
Mixon was not invited to the NFL scouting combine last month due to his season-long suspension three years ago for punching a woman.
