The Raiders have placed 25-year old OLB Ricky Brown on the Injured Reserve List with a bum ankle ending his season.  Brown played in 5 games for the Raiders this season and he had 31 tackles, 1 forced fumble and he defensed 2 passes.  He has now played in 41 games in his 4 years with the Raiders and he has made 89 tackles, defensed 3 passes and he forced 2 fumbles.  The Raiders should be able to replace Brown but he was playing pretty decent this year.
