"Update: 11:00 a.m.
U-T San Diego is reporting that Mathews was not arrested. Sgt. Robin Rose of the San Diego Police Department refuted the Examiner’s report that Mathews was taken in after a bar fight Sunday evening.
“We can say that he was definitely not arrested by SDPD,” Rose said, “but there might have been a separate arrest that lead to that (report). … It was not Ryan Mathews.”"
