Lost star Naveen Andrews has signed on to film a guest spot on an episode of Law & Order: SVU, TVGuide.com has learned exclusively.

The details of his role are being kept under wraps for now, but the episode starts filming in the next week or so in New York.

Andrews, 40, plays Sayid Jarrah on ABC's Lost, which is still shooting its final season in Hawaii. (A source tells us they're on Episode 6 of 18.)

Let's not jump to any conclusions though. "As with previous seasons, not all cast members are in every episode," says a studio rep. It's entirely possible that Andrews will finish his SVU gig and return to Hawaii to shoot more Lost. But the timing does at least raise the question: Is Andrews, and thus Sayid, done for the season?

Before Lost, Andrews was best known for playing a sensitive explosives expert who wooed Juliette Binoche in Anthony Minghella's The English Patient.

Andrews' SVU episode will air in January 2010, right around the time that Lost's sixth and final season premieres.
