Roth in, Crowder out for Dolphins

Posted by ESPN.com's Tim Graham

The Miami Dolphins have tinkered with their roster in preparation for Sunday's sequel with the New York Jets at the Meadowlands.

Miami activated outside linebacker Matt Roth from the non-football injury list and released rookie tight end John Nalbone, a fifth-round draft choice.

Miami also downgraded inside linebacker Channing Crowder from doubtful to out because of a shoulder injury. The move extricates one of the more entertaining characters from a game that's compelling, in part, because of his vitriol.

As mentioned on this blog a few days ago, Jets coach Rex Ryan metaphorically will step over Crowder on his way to a fight. Crowder has been unable to practice since hurting his shoulder in last week's loss to the New Orleans Saints.

Roth's return is good news for the Dolphins' defense and ends a weird ordeal. Roth started 14 games last year but showed up to camp with a mysterious condition. The team claims Roth informed them he was ill, but agent Drew Rosenhaus declared Roth had a groin injury.

Roth was placed on the reserve list and was eligible to be activated last week. But he suffered an ankle injury and remained on the shelf.
