Miami saws Bobby Carpenter off the roster

A week and a half ago, New York Jets special teams coordinator Mike Westhoff all but outed Miami Dolphins linebacker Bobby Carpenter as the chief culprit for the atrocious special-teams performance that forced the Dolphins to fire coordinator John Bonamego.

The Dolphins finally terminated Carpenter's contract Monday.

Carpenter was a 2006 first-round pick for the Dallas Cowboys when Bill Parcells was head coach. The Cowboys traded Carpenter to the St. Louis Rams in May. The Rams released him before the season, and the Dolphins snatched him up Sept. 6, making him their final acquisition before Parcells stepped down as Dolphins vice president of football operations.

Carpenter had been weak on special teams and became even more expendable when inside linebacker Channing Crowder returned from a groin injury Sunday against the Green Bay Packers.

Carpenter played five games for the Dolphins, starting the first two. Carpenter made only six defensive tackles by the team's unofficial count. He was tied with Tyrone Culver for the lead with four special-teams tackles. He downed a pair of punts inside the 20-yard line, most on the club.

But without naming names, Westhoff provided enough information to identify Carpenter as responsible for giving up a blocked punt and for missing a tackle on what turned into a kickoff return for a touchdown by the New England Patriots in Week 4.

Carpenter appeared to miss another assignment Sunday that let a Packers defender deflect a Brandon Fields punt.

The Dolphins released linebacker Erik Walden after he allowed a blocked punt against the Jets in Week 3.
