A trio of Pro Bowlers have skipped all of the Colts voluntary workouts this offseason and coach Jim Caldwell isn't sure if they'll be at this weekend's mandatory mini-camp. Indianapolis wide receiver Reggie Wayne doesn't typically participate in voluntary workouts and has been dealing with legal issues. Defensive end Robert Mathis reportedly wants to renegotiate his contract, while safety Antoine Bethea has not signed his one-year tender with the Colts.
