Joey Porter's wish was granted Friday by the Miami Dolphins: They released him.

The four-time Pro Bowl linebacker campaigned last week to be waived, saying in broadcast interviews he was frustrated about his reduced role in 2009 and doubted his relationship with coach Tony Sparano could be repaired.

Mike Florio of profootballtalk.com thinks Porter could be a good fit for the Cowboys.

"The Cowboys could be an alternative, if Porter is willing to accept a backup role behind DeMarcus Ware or Anthony Spencer. Former Dolphins defensive coordinator Paul Pasqualoni, who worked with Porter each of the past two years, has returned to the defensive staff in Dallas.

"Of course, there's a chance that anyone who has worked with Porter will want to have nothing further to do with him."

As his role diminished, Porter said, he talked with Sparano only on Sundays and stopped speaking with general manager Jeff Ireland and football czar Bill Parcells. Porter said he was the Dolphins' best outside linebacker and unhappy about being replaced by pass-rush specialist Cameron Wake in some situations. He said he wanted to go to a team where he could play every down.

Porter said he saw less playing time after Sparano held him out of a midseason game at Tampa Bay because he "went out to get something to eat" two nights before the game. The defense deteriorated at the end of the season, and Miami failed to make the playoffs, finishing 7-9.
