Just because William Petersen signed a contract in May that said he was going to stay on CSI, doesn't mean that he's going to, you know, stay on CSI. As it turns out, Petersen, who does double-duty as Gil Grissom and executive producer of the long-running procedural, had a clause in his contract that is allowing him to leave the show after this season's tenth episode. Both Petersen and CBS are quick to point out, however, that we will not be seeing the last of Gil Grissom.

Petersen plans to remain actively involved in CSI and is maintaining his role as executive producer. Although he will no longer be a series regular, he's definitely not planning on leaving for good, saying, "I'm in a great place in terms of knowing that I'll be more free to make choices. And I'm responsible enough to not do it in a way that would hurt [the show]."
