There have been quite a few TV departures lately -- some more shocking than others.

Somewhere in the middle there is Laurence Fishburne's announcement that he's leaving his post at 'CSI' after only two and a half years. Fishburne, who played lead investigator Raymond Langston, replaced series star William Petersen, who started as Gil Grissom when the series premiered 11 seasons ago.

Those were some pretty big shoes to fill at the time -- and Fishburne didn't always seem too thrilled at the comparisons -- but now who will be the third person to take the job? And how will the show look with lead actress Marg Helgenberger taking a lesser role next season, too?

We've brainstormed some good men -- and one lady -- for the position. Keep reading and share your own casting thoughts in the comments.

It's not exactly a full season pick up, but NBC has ordered some more episodes of Friday Night Lights. It's not clear how many episodes, since The Hollywood Reporter is saying 'six' and Broadcasting and Cable is saying 'nine'. The teen-age football drama is doing poorly in the ratings on Tuesday nights but NBC obviously believes in the series. The network will air a new episode of Friday Night Lights on Monday, October 30th in place of a planned repeat of Studio 60 on the Sunset Strip. NBC is hoping Heroes' viewers will hang around to see the football drama. It's hard to have any hope about that show during that Monday night slot, since it's in competition with Monday Night Football on ESPN.

I think the problem with the show is that it's about football. It seems to target the teen-age crowd that watches The O.C. and Laguna Beach, but those two shows are very different. The O.C. is an overly-dramatic series about ridiculously rich kids, which happens to be a fetish amongst American television viewers.
