The Lions announced they have signed safety Louis Delmas to a four-year contract on the day before players report to training camp.
   Delmas, a second-round pick from Western Michigan, made the most of his offseason workouts, impressing coaches and possibly earning a starting role.
  The Lions also announced they released veteran defensive end Eric Hicks.
    Still unsigned are first-round tight end Brandon Pettigrew, third-round wide receiver Derrick Williams and fourth-round defensive tackle Sammie Hill.
   Players report at 4 p.m. on Friday with the first workout set for Saturday afternoon.
