Alex O'Loughlin navigates 'Three Rivers'

'Moonlight' star returning to CBS with medical drama pilot

Alex O'Loughlin is returning to CBS.

The "Moonlight" star is in negotiations to star on the network's medical drama pilot "Three Rivers."

The project, from CBS Paramount, is about organ transplants seen through three points of view: the doctors, the donors and the recipients.

O'Loughlin will play Dr. Andy Yablonski, the workaholic head of the team of organ donor transplants who is separated from his wife and lives in a motel near the hospital.

"Three Rivers" is one of three medical pilots CBS has greenlighted this season with the hopes to launch one as a series in the fall. The other two are "Miami Trauma" and the more family-centric "The Eastmans."

Aussie O'Loughlin, repped by ICM and manager Andy Freedman, developed a cult following with his role as sexy vampire Mick St. John on CBS' "Moonlight."

He joins Skeet Ulrich, the star of another CBS drama with a other huge cult hit, "Jericho," who also signed up to topline a drama pilot for the network.

Ulrich is starring in the mystery "Back."
