Julie Finlay won’t be around when the CSI gang reunites this fall.

EW has learned exclusively that Elisabeth Shue, who has played Finlay on the CBS drama since 2012, will not participate in the show-wrapping two-hour special planned for Sept. 27. It’s unclear how the producers will handle Finlay’s absence from the show’s swan song.

The special is expected to include the return of original series star William Petersen as Gil Grissom. Marg Helgenberger will also reprise her role as Catherine Willows.

In the meantime, current CSI star Ted Danson will continue to stay with the franchise by moving over to the show’s latest spin-off, CSI: Cyber.
