Adina Porter to Save Lives on Grey's Anatomy

Adina Porter is set to scrub in on Boise Hospital ... er, Grey's Anatomy.

The True Blood and Newsroom star will appear in the second episode, which features a flashback to how the doctors were rescued after the plane crash (see star Ellen Pompeo's interview for more on this subject).

Grey's Anatomy Season 9 picks up months after the crash, then flashes back to the immediate aftermath the following week. Porter will play Dr. Ramsey, the Boise Hospital doctor that treats the survivors after the crash.

Porter played Tara's mom on True Blood and Kendra James, booker for "News Night" on Newsroom.

Porter joins previously cast Grey's Anatomy guest stars, including Tina Majorino, Gaius Charles, Camilla Luddington, Dominic Hoffman and newcomer Tessa Ferrer, all of whom will appear in Seattle on Season 9.
