LSU has dismissed Heisman Trophy finalist Tyrann Mathieu from its football program for violating school and team rules.
   The junior defensive back nicknamed Honey Badger was a surprising Heisman Trophy candidate last season as the Tigers won the Southeastern Conference championship and reached the BCS title game. LSU lost the championship 21-0 to Alabama.
   At a news conference Friday, coach Les Miles would not specify the reason Mathieu was kicked off the team.
