Fins scratch Porter, but not for injury

Miami Dolphins outside linebacker Joey Porter won't be running down ball carriers -- or his mouth -- Sunday against the Tampa Bay Buccaneers.



The team confirmed Porter has been scratched because of a coach's decision, not because Porter is hurt. He missed two days of practice with a knee injury, but when he came back he was listed as probable for the game.

There's mystery surrounding head coach Tony Sparano's decision.

Is it performance-related? Porter has only 2.5 sacks this year and had zero tackles last week against the New England Patriots.

Is it because Porter has been yapping too much? Sparano hasn't expressed any qualms with Porter's boisterousness before.

Porter's absence will give Matt Roth and Cameron Wake a greater opportunity to get involved. Roth recently was activated off the non-football injury list. Wake ranks third on the Dolphins with 3.5 sacks even though he was deactivated for the first two games and saw limited snaps compared to Porter and Jason Taylor.

Porter has 17.5 sacks last year to lead the AFC and finish second only to DeMarcus Ware.
