Criminal Minds Cuts A.J. Cook, Will Add New Cast Member, Source Says

A.J. Cook has been dropped from Criminal Minds and will be replaced by a new female cast member during the CBS drama's upcoming sixth season, a source close to the show tells TVGuide.com.
The source cited "creative reasons" for Cook's departure, not financial considerations by the network as initially cited.
 
Cast member Paget Brewster is in negotiations to return for a reduced number of episodes. Thomas Gibson, Joe Mantegna, Shemar Moore, Matthew Gray Gubler and Kirsten Vangsness are all expected to return.
