The Raiders have signed DE Kalimba Edwards.  Edwards played in 8 games (6 starts) for the Lions last season and he made 17 tackles and had 3 sacks.  Edwards has now played in 87 games (22 starts) in his NFL career and he has made 160 tackles, has 26 sacks and he has defensed 10 passes.  This was a good move for the Raiders who needed some pass rush help.
