Much roster adjusting for Dolphins on Sat.

NEW YORK -- The Dolphins are in Gotham, well, on the New Jersey outskirts across the river, and they are busy.

They have downgraded ILB Channing Crowder to out for Sunday's game against the Jets. Reggie Torbor is expected to start in Crowder's place on Sunday. Crowder is nursing a left shoulder injury and missed the entire week of practice.

The Dolphins thus have an open spot on the active game day roster and that is likely to be taken up by LB Matt Roth, who was activated onto the active roster on Saturday. To make room for Roth on the 53-man roster, the club waived TE John Nalbone.

Nalbone will now go through the waiver process. It is possible if another team doesn't claim him, he could be signed to Miami's practice squad next week.

In the meantime, it will be interesting to see if Roth, who has not played this season while he was on the non-football injury list, is used on special teams, as an outside linebacker or even gets snaps at inside linebacker. It is possible he will do all three.

Roth, you should remember, suffered a mysterious groin injury just prior to the opening of training camp. He missed all of training camp as a result and was placed on NFI as a result. He became eligible to start practicing against after the sixth week of the NFL season, and after missing some more time with a tweaked ankle, he returned to practice and worked all of this past week.

Roth was Miami's starting strongside linebacker in 2008, the job Jason Taylor has won this year.
