As was reported here months ago Mike Walker is still having problems with his knee that he had surgery on two seasons ago.  He has been placed on the Injured Reserve List and will miss the entire 2007 season for the Jaguars.  He did play in the pre-season and he caught 4 passes for 33 yards (8.3 avg).  This is a shame for both Walker and the Jaguars as they have one of the worst receiving corps in the NFL.
