A man has been arrested for apparently slapping Bears wide receiver Devin Hester in the head.  Des Plaines police tell the "Chicago Tribune" Daniel Rago smacked Hester Friday night at the Rivers Casino.  They're not sure why Rago hit Hester, nor has any motive been given.  Police added Hester was very professional and contacted security, who called police.  Rago is charged with battery and has a December 1st court date.
