Former NFL wide receiver Keyshawn Johnson won't be facing charges in connection to an incident involving his ex-girlfriend in the Los Angeles area.  Prosecutors have decided not to file charges against Johnson involving he and his ex at his Calabasas home.  Johnson had been arrested last month on battery charges after the girlfriend said she had been injured by the former NFL star during a fight over a phone.  Prosecutors say the girlfriend didn't cooperate with the subsequent investigation.
