The Raiders have released 31-year old DT Gerard Warren.  Warren played in all 16 games for the Raiders last season and he made 35 tackles, 3 tackles for a loss, he had 2 sacks and he defensed 1 pass.  He played in 44 games in three years with the Raiders in which he had 96 tackles, defensed 3 passes, had 10 sacks and he forced 2 fumbles.  Due to the Raiders’ performance against the run last season I look for them to gut the entire interior of the defense and Warren was the first to go.
