Chargers running back Ryan Mathews was not arrested Sunday night, San Diego police said Monday morning, contrary to a report alleging his involvement in a fight outside a San Diego night club. The officer confirmed an report of an 8:30 p.m. fight outside Side Bar, located in the Gaslamp district on 536 Market St. A Chargers spokesman said the team was aware of the report and working to confirm Mathews' reported role. Sgt. Robin Rose directly refuted it, saying Mathews was not arrested.
