The Saints will be without starting CB Tracy Porter for the next 4-8 weeks with a sprained MCL.  This will hurt the Saints’ D big time as Porter has been a playmaker this season.  He has played in 9 games for the Saints this season and he has 43 tackles, 2 forced fumbles, 8 passes defensed and he has three interceptions (one of which he returned for a TD).  Rookie CB Malcolm Jenkins will replace Porter in the starting lineup.  Jenkins has played in 7 games for the Saints this season and he has 10 tackles and two forced fumbles.  Teams will be attacking Jenkins early and often in games so the Saints need him to step up.
