LOS ANGELES -- Sara Sidle is coming back to "CSI: Crime Scene Investigation."

Actress Jorja Fox, who left the crime drama as a regular two years ago, will return as Sara for the 10th-season debut and other episodes, CBS said Friday.

"We're thrilled for Jorja's return to 'CSI,"' said executive producer Carol Mendelsohn, adding that viewers will "discover where life has taken Sara Sidle and what brings her back to the 'CSI' team in Las Vegas in our premiere episode."

The show returns Sept. 24.

Fox, part of "CSI" since the show started, left during its eighth year. She was seen briefly last season, including one episode in which her character reunited with ex-colleague and romantic interest Gil Grissom, played by William Petersen.

Petersen left the series last season, with Laurence Fishburne joining the cast. CBS didn't say whether Petersen might drop back in next season along with Fox.

'CSI' airs in Canada on CTV.
