The Chiefs have signed 25-year old linebacker Corey Mays.  Mays played in 12 games for the Bengals last season and he made 16 tackles and forced a fumble.  He has now played in 32 games in his NFL career and he has made 41 tackles, defense 1 pass and forced a fumble.  This will help out depth at linebacker and Mays is also a solid special teams player so he should help the Chiefs some in 2009.
