The Lions have placed 24-year old linebacker Jordon Dizon on the Injured Reserve List with a knee injury.  Dizon had 1 tackle against the Steelers in the pre-season opener.  He played in 16 games for the Lions last season and he had 29 tackles, 1 forced fumble and 1 sack.  Dizon has played in 28 games in his two years with the Lions and he has 57 tackles, 1 sack and 1 forced fumble.  Dizon’s loss will hurt the Lions’ depth at linebacker and the special teams.
