The Dolphins have placed starting linebacker Channing Crowder on I.R. with a right foot injury ending his season.  Crowder played in 13 games for the Dolphins last season and he made 51 tackles, 3 tackles for a loss, he had 1 sack and 1 interception.  28-year old Reggie Torbor will be replacing Crowder in the starting line-up.  He has played in 15 games this season for the Dolphins and he has made 32 tackles, 3 tackles for a loss, 1 sack, defensed 4 passes and he has 1 interception.  The pass defense will probably improve a tad while the run defense regresses a tad making this essentially a wash.
