CSI definitely welcomes Katee Sackhoff to the cast next week. It might also welcome a Tyrannosaurus Rex.

The former Battlestar Galactica actress will debut as Detective Frankie Reed, as she assists the CSI team on an unusual case: a man appears to have been killed by a dinosaur. Will this be another instance of the show getting too silly for its own good?

Or, like last night's installment, will it take on an unusual case in an interesting way? Tune in. Find out. And watch the preview below to prepare for "Cold-Blooded."
