Jerramy Stevens re-injured his left knee in practice Thursday.  He had minor surgery on that knee in April and will have more surgery on Friday.  The injury could knock him out for six weeks, leaving a possible return date of October 8th.  Ituli Mili will take over as the starter.  Stevens really emerged last season when Mili got hurt, so now it’s Mili’s turn to step up.  With Darrell Jackson already hurtin’, they need production in the passing game from the tight-end.
